Technical Field

The present invention relates to the technical field of medical care and health, and in particular, to a flexible sensor detection system for medical care and health.

Related Art

The description in this section merely provides background information related to the present invention and does not necessarily constitute the prior art.

With the rapid development of science and technology today, convenience, intelligence, and environmental protection have become the development themes of various industries. Traditional medical treatment exists as a special industry. The uniqueness and closeness of the system of the traditional medical treatment increasingly expose shortcomings of traditional medical procedures, which cannot keep up with needs of people.

With the rapid development of sensing technologies and the gradual penetration of internet technologies into various fields, the combination of medical care and health fields with the sensing technologies and the internet can improve the disadvantages of a traditional medical treatment mode, and has great practical significance. The sensing technologies can measure a biological signal of a user, and transmit information to a device or an institution by information transmission, and give feedback to the user with an analysis of the information by the device or institution. Therefore, an internet-based wearable intelligent sensing device emerges at the right moment.

One of the most important parts of the wearable device is an information collection part, and whether a sensor used for information collection is flexible or rigid determines a comfort level and a measurement accuracy of the wearable device. A flexible sensor has two characteristics of being comfortable and accurate when being used in the medical care and health fields. A Rigid sensor is basically flat, hard and undeformable, and form a point-to-face, hard-to-soft contact interface when being integrated in a human body. In contrast, a flexible sensor is soft, deformable, and easy to form a face-to-face, soft-to-soft contact interface when being integrated in a human body, thus implementing more comfortable and accurate medical care and health monitoring.

At present, many patents have conducted researches on the wearable intelligent sensing device. For example:

The prior art discloses an intelligent sensing vest. The vest is used as a carrier. A chest breathing band is arranged below a chest of the vest, an abdominal breathing band is arranged at an abdomen position, a snapping-type sensor connection port is arranged outside the chest position, a battery connection port is arranged at a middle of a right shoulder band, and the chest breathing band and the abdominal breathing band support collection of a heart rate, an electrocardiogram and a breathing parameter. A wireless sensor is installed at the sensor connection port, and the wireless sensor is used for sending a physical sign parameter collected by the chest breathing band and the abdominal breathing band to an external monitoring device through wireless transmission of an electrical signal.

The prior art discloses a wearable physiological sensing device. Using a wristband as a carrier, the device is provided with an index collection and calculation unit, a microprocessor unit, a data storage unit, a wireless sending unit, a power management unit, a vibration sensor, a wireless receiving unit, and a display device.

The prior art discloses a single-chip-based intelligent wearable device, which includes a control module, a gesture detection module, a temperature collection module, a communication module, and a display module. The temperature collection module and the gesture detection module detect a physical sign signal of a user in real time and send the signal to the control module for processing. The control module determines a human body activity state according to the signal sent by the gesture detection module, displays a determination result in the display module, and sends the result to an upper computer through the communication module.

In the wearable intelligent sensing devices, the information measured by the sensor is stored by a storage device and transmitted to an external monitoring device wirelessly, but a clear feedback is not given to the user. In addition, use of a lithium polymer battery has also caused a certain degree of environmental pollution.

The prior art discloses an intelligent medical system based on a Zigbee technology. The system includes a first sensor module, a second sensor module, an alarm module, an intelligent watch, and a plurality of Zigbee coordinators. Each Zigbee coordinator is communicated with a server through a gateway device. The first sensor module is configured to detect a condition of a ward, the second sensor module is configured to detect a condition of a corridor outside the ward, and the intelligent watch is used to detect a physiological condition of a patient in the ward. The first sensor module, the second sensor module, and the alarm module communicate with the server through the Zigbee coordinators, and the intelligent watch directly communicates with the server through the gateway device, so as to implement temperature and humidity detection as well as fire monitoring and alarming in the ward. In addition, a doctor and a nurse can query detailed information of the patient.

This monitoring system is limited in a certain space, and cannot carry out real-time medical monitoring on the user in any space.

In this embodiment, the adjustable buttons are made of plastic in view of weight. The adjustable buttons can adjust sizes of the vest, the wristband and the headband to meet different body types and make people feel comfortable. In addition, the adjustable buttons at the shoulder bands of the vest can also adjust the shell temperature band, so that the shell temperature band at the armpit position can be accurately located under the armpits of people with different physical signs, thus increasing the measurement accuracy. The adjustable buttons at the boundary between the vest left front piece and the left side of the vest back piece and at the boundary between the vest right front piece and the right side of the vest back piece can make the heart rate ECG band and the breathing band close to the human body, so that relevant physical sign signals are conveniently collected. The adjustable buttons at the wristband can make the blood flow rate band and the blood glucose band close to the skin, so that relevant physical sign signals are conveniently collected. The adjustable buttons at the headband can make the blood oxygen band and the deep temperature band close to the skin, so that relevant physical sign signals are conveniently collected.

In this embodiment, the heart rate ECG band internally contains a transformer, a flexible heart rate sensor, a signal amplifying circuit, an A/D converting circuit, a flexible ECG sensor and an AD8232 chip. The breathing band internally contains a transformer, a capacitor three-point resonant circuit, a flexible breathing sensor, and a breathing control chip. The shell temperature band internally contains a transformer, a signal amplifying circuit, an A/D converting circuit, and a deep temperature control chip. The blood flow rate band internally contains a transformer, a flexible blood flow rate sensor, and a blood flow rate control chip. The blood glucose band internally contains a transformer, a flexible blood glucose sensor and a blood glucose control chip. The blood oxygen band internally contains a transformer, a flexible blood oxygen sensor and a blood oxygen control chip. The deep temperature band internally contains a transformer, a flexible deep temperature sensor, a signal amplifying circuit, an A/D converting circuit, and a deep temperature control chip.

The flexible shell temperature sensor, the flexible heart rate sensor, the flexible breathing sensor, the flexible blood flow rate sensor, the flexible blood glucose sensor, the flexible blood oxygen sensor, and the flexible deep temperature sensor are each made of a flexible base layer, a functional layer and a flexible encapsulation layer, which are installed on an inner surface of a carrier, so that the sensors are in direct contact with a human body surface. Therefore, it is necessary to consider not only stretchable and compressible characteristics of the sensor, but also a biocompatibility between the sensor and the human body. Therefore, materials used for the flexible substrate and the encapsulation layer shall satisfy the following points:

(1) the materials shall have excellent elastic mechanical properties;

(2) the materials shall have excellent waterproof and breathable effects; and

(3) the materials can adapt to a complicated morphology of the human body surface.

In this way, the following can be achieved:

(1) the sensors can improve the measurement of the physical sign parameters of the human body;

(2) sweat secreted by skin sweat glands under the sensing devices can be discharged into the air through the devices in the form of steam, so as to avoid the accumulation of sweat to form impregnation; and

(3) outside air can pass through the devices to reach a skin surface to complete a breathing activity on the body surface.

Meanwhile, the materials have good water resistance, so that neither external liquid nor sweat on the body surface can enter the functional layers of the devices to result in short circuit failure.

The functional layers of different flexible sensors are different. For the functional layers of the flexible shell temperature sensor and the flexible heart rate sensor, a “snake-shaped” interconnection structure may be constructed, which has good mechanical properties. For the materials of the functional layer, metal with good physical properties may be selected or a conductive filler may be doped in a polymer to obtain sensitive materials with higher physical properties. Layered structures of the flexible shell temperature sensor and the flexible heart rate sensor are as shown in FIG. 11, including: an encapsulation layer 11-1 of the flexible shell temperature sensor and the flexible heart rate sensor, a functional layer 11-2 of the flexible shell temperature sensor and the flexible heart rate sensor, and a base layer 11-3 of the flexible shell temperature sensor and the flexible heart rate sensor.

The flexible shell temperature sensor and the flexible heart rate sensor are served as inductive elements of shell temperature and heart rate circuits. When the functional layer receives temperature or vibration signals, resistance of the inductive elements changes accordingly, causing current changes, thus converting the temperature or vibration signals into electrical signals. After signal amplification and A/D conversion, physical parameters of shell temperature and heart rate are obtained and stored in the vest main control chip 2-15.

The functional layer of the flexible deep temperature sensor also adopts the “snake-shaped” interconnection structure. For the materials of the functional layer, metal with good physical properties may be selected or a conductive filler may be doped in a polymer to obtain sensitive materials with higher physical properties. A layered structure of the flexible deep temperature sensor is as shown in FIG. 12, including: an encapsulation layer 12-1 of the flexible deep temperature sensor, a functional layer 12-2 of the flexible deep temperature sensor, an isolation layer 12-3 of the flexible deep temperature sensor, and a base layer 12-4 of the flexible deep temperature sensor. The two flexible temperature sensors are integrated and separated by a polymer. A measurement principle is to use a differential measurement mode of a plurality of temperature sensors to measure the deep temperature of the human body in a non-intrusive manner. The flexible deep temperature sensor is served as an inductance element of a deep temperature circuit. When the functional layer receives temperature signals, resistance of the inductive element changes accordingly, causing current changes, thus converting the temperature signals into electrical signals. After signal amplification and A/D conversion, a temperature value is obtained. The deep temperature control chip calculates a deep temperature according to the measured temperature value through a corresponding algorithm and transmits the deep temperature to the headband main control chip 8-3.

The functional layer of the flexible breathing sensor adopts an insulated coil bent into a certain shape. The coil needs to form a closed loop in the chest and abdomen of the user respectively, as shown in FIG. 13. The coil is served as an inductive element of a capacitor three-point resonant circuit. A breathing movement causes the change of inductance of the coil, which leads to the change of resonance conditions of a resonant circuit, thus causing a resonance amplitude and a resonance frequency to change with the breathing movement. The breathing control chip is used for analyzing and processing the resonance amplitude and the resonance frequency, obtaining physical sign parameters of the breathing movement by frequency modulation-detection, and transmitting the parameters to the vest main control chip 2-15.

A connector interface 2-13 of the breathing band at the chest position and a connector interface 2-14 of the breathing band at the abdominal position connect the flexible breathing sensors in the chest breathing band 3-2 and the abdominal breathing band 3-3 to form a closed sensor around the human body by one circle to make the sensor work normally.

A working principle of the flexible blood flow rate sensor is to measure the blood flow rate by a thermal method, which will cause temporal and spatial distribution and changes of a temperature field on the body surface, and can deduct the blood flow rate by monitoring the changes through the temperature sensor, combining with a heat transfer model or a correlation analysis.

The functional layer of the flexible blood flow rate sensor is as shown in FIG. 14. A central position of the functional layer is provided with a central heater 14-3 for artificially manufacturing a temperature rise of the body surface, and two circles of temperature sensors 14-2 are distributed around the functional layer for measuring the temperature field. The blood flow rate control chip is used for controlling the heating of the central heater, analyzing and processing the temperature field information measured by the temperature sensor to obtain physical sign parameters of the blood flow rate, and transmitting the parameters to the wristband main control chip 5-3 through a signal wireway 14-1.

The functional layer of the flexible blood glucose sensor includes a glucose sensor and a paper battery coated with a high-concentration hyaluronic acid at an anode. Glucose in a tissue fluid is extracted by using an electrochemical double-channel method, and is sensed and measured by the glucose sensor. The blood glucose control chip analyzes and processes the data measured by the glucose sensor and transmits the processed data to the wristband main control chip 5-3.

The functional layer of the flexible blood oxygen sensor is composed of a red and infrared LED and a photodetector. The red and infrared LED is served as a light source. The photodetector can obtain a light absorption degree and a light scattering degree of the blood according to an action of the blood on the light. The blood oxygen control chip analyzes and processes the data measured by the photodetector to obtain blood oxygen parameters and transmits the parameters to the headband main control chip 8-3.

A preparation process of the flexible sensor is as shown in FIG. 15. Firstly, a sensitive material is processed into a desired functional layer shape by a photoetching technology, and then the processed functional layer is moved to a flexible substrate by a transfer printing technology. Moreover, a conductive metal is photoetched into a desired electrode shape, and finally, the electrode and the sensitive layer on the flexible substrate are flexibly encapsulated to prepare the flexible sensor.

FIG. 16 is a diagram of a photoetching technology, where main steps of the photoetching technology are as follows:

(1) cleaning a substrate: a traditional photoetching technology requires a material substrate to be flat, while a flexible material such as polyimide needs to be pretreated during photoetching; the flexible material such as polyimide needs to be adhered to the clean substrate as a donor substrate; and moreover, the substrate is cleaned in a plurality of steps to ensure tight adhesion and avoid deviation caused by pollution during photoetching;

(2) sputtering and depositing a sensitive layer: sputtering and depositing a sensitive material on the donor substrate to form a sensitive layer, where depositing techniques include chemical vapor deposition, physical vapor deposition and the like; and a suitable depositing method is selected according to different deposited materials;

(3) gluing, exposuring and developing: designing a mask plate according to a needed pattern; uniformly coating photoresist on a surface of the sensitive layer by adjusting a rotating speed of a spin coater, and patterning the photoresist through the mask plate by the steps of dewatering baking, soft baking and hard baking, where the photoresist disappears in an exposed part, the sensitive layer is exposed, and the photoresist still exists in an unexposed part;

(4) graphically etching the sensitive layer: etching the sensitive layer not covered by the photoresist by an etching solution to implement transfer of a mask plate pattern to a sensitive layer pattern; and

(5) removing the photoresist and cleaning: washing with an acetone solution to remove residual photoresist and organic matters on a metal layer, and finally obtaining the desired functional layer pattern.

FIG. 17 (a) to FIG. 17(d) are process diagrams of the transfer printing technology, and the main steps of the transfer printing technology are as follows:

(1) preparing a desired functional layer pattern 17-2 on a flexible material like polyimide as a donor substrate 17-3 through a photoetching technology;

(2) processing a flexible stamp 17-1 made of polydimethylsiloxane and a surface of the functional layer pattern 17-2 to be transferred according to a set requirement, attaching the flexible stamp 17-1 closely to the functional layer 17-2, and tearing up the flexible stamp 17-1 from the donor substrate 17-3 at a high enough speed to ensure that an adhesive force between the flexible stamp 17-1 and the functional layer 17-2 is large enough, so that the functional layer 17-2 can be torn up along with the flexible stamp 17-1;

(3) attaching the flexible stamp 17-1 adhered with the functional layer 17-2 closely to a surface of a processed acceptor substrate 17-4, and extruding for a certain period to form an adhesive force between the functional layer 17-2 and the surface of the acceptor substrate 17-4; and

(4) slowly tearing up the flexible stamp 17-1 to ensure that the functional layer 17-2 to be transferred remains on the acceptor substrate 17-4.

A flexible fabric electrode is used for a flexible ECG sensor to convert bioelectric signals into hardware measurable electrical signals, and an AD8232 integrated with operational amplifier, ADC digital-to-analog conversion, DSP digital filtering and heart rate detection algorithms as a front-end conditioning chip of ECG signals. The AD8232 analyzes and processes the signals measured by the flexible fabric electrode and transmits the processed ECG signals to the vest main control chip 2-15.

Measurement principles of the flexible heart rate sensor and the flexible breathing sensor may also be implemented based on piezoelectric effect. A flexible piezoelectric film material may be polyvinylidene fluoride with good piezoelectric properties and high flexibility, and the electrode may be made of metal with good physical properties. Layered structures of the flexible heart rate sensor and the flexible breathing sensor are as shown in FIG. 18, including: an encapsulation layer 18-1 of the flexible heart rate sensor and the flexible breathing sensor based on piezoelectric effect, an upper electrode 18-2 of the flexible piezoelectric film, the flexible piezoelectric film 18-3, a lower electrode 18-4 of the flexible piezoelectric film, and a base layer 18-5 of the flexible heart rate sensor and the flexible breathing sensor based on piezoelectric effect. The upper electrode 18-2 of the flexible piezoelectric film, the flexible piezoelectric film 18-3, and the lower electrode 18-4 of the flexible piezoelectric film constitute the functional layer of the flexible heart rate sensor and the flexible breathing sensor. The flexible heart rate sensor and the flexible breathing sensor are served as sensing elements of heart rate, breathing and blood pressure circuits. When the functional layer is excited by heart beating and breathing movement of a user, the flexible piezoelectric film bends. Piezoelectric charges are generated at the moment of bending, and a potential difference is generated between the upper and lower electrodes. In this way, heart rate and breathing signals of the user are converted into electrical signals. Then, the electrical signals stored with heart rate and breathing information are transmitted to the AD8232 chip and the breathing control chip respectively. After being analyzed and processed by the AD8232 chip, the breathing control chip and a blood pressure chip, the physical sign parameters of heart rate and breathing of the user are obtained and transmitted to the vest main control chip 2-15.

The flexible piezoelectric film is prepared by an electrostatic spinning method, and an electrostatic spinning technology is as shown in FIG. 19.

(1) A flexible substrate is prepared, and placed below an electrospinning needle as a collecting device of the flexible piezoelectric film, where the flexible substrate is made of polydimethylsiloxane with good flexibility.

(2) Under the action of a high-voltage electric field applied by a power supply, a surface of a piezoelectric polymer solution or a melt in a syringe pump generates electric charges, and under the combined action of an electric field force and a surface tension, a conical droplet is formed on the electrospinning needle, and is called a Taylor cone. If the voltage is continuously increased, the charged conical droplet overcomes the surface tension and is gradually lengthened and thinner, breaking through a cone top and shooting at a collection substrate, and finally forming a fibrous piezoelectric film.

(3) Generally, most of the prepared piezoelectric films are spiral nonpolar α-phases, which are stable in structure but not piezoelectric. It is necessary to apply a tensile stress or a high-intensity electric field to the films, so that randomly oriented molecular dipole moments in the piezoelectric film are aligned in a specific direction, thus forming a β-phase with good piezoelectric properties.

The adjustable button 2-6 of the left shoulder band and the adjustable button 2-7 of the right shoulder band can adjust a longitudinal size of the vest. The adjustable button 2-8 below the left chest, the adjustable button 2-10 on the left abdomen position, the adjustable button 2-9 below the right chest and the adjustable button 2-11 on the right abdomen position can adjust a lateral size of the vest. The wristband adjustable button 5-2 can adjust a diameter of the wristband. The headband adjustable button 8-2 can adjust a diameter of the headband. In this way, the vest can meet physiques of different users to increase the comfort level. Moreover, each flexible sensor can be closely attached to the human body surface by the adjustable buttons, thus increasing the measurement accuracy.

The left battery unit 4-1 and the right battery unit 4-2 adopt a principle of thermal-electrical conversion. When a P-type semiconductor and an N-type semiconductor form a loop, in the presence of an external load, if temperatures at two end faces of the P-type semiconductor and the N-type semiconductor are different and a temperature difference occurs, then a voltage and a current may be generated in the loop, where the P-type semiconductor is an anode of the battery and the N-type semiconductor is a cathode of the battery. The vest designed only works at a normal ambient temperature. According to an ambient temperature of the vest, a low-temperature thermoelectric material Bi2Te3 is selected. Adding a proper amount of Se to Bi2Te3 may obtain the N-type semiconductor needed by the thermoelectric conversion device, and adding a proper amount of Sb to Bi2Te3 may obtain the P-type semiconductor needed by the thermoelectric conversion device, where chemical formulae of the semiconductors are as follows:

Bi₂Te₃+Se→Bi₂Te_3-xSe_x(N-type semiconductor)

Bi₂Te₃+Sb→Bi_2-xSb_xTe₃(P-type semiconductor)

FIG. 20(a) and FIG. 20(b) show two types of thermal-electrical conversion circuits, both of which take an outer side of a metal 2 as a high-temperature heat source and an outer side of a metal 1 as a low-temperature heat source to carry out analysis. Only the up-down order of the metal 1 and the metal 2 is changed, and it is found that circuits in FIG. 20(a) and FIG. 20(b) each use the P-type semiconductor as the anode and the N-type semiconductor as the cathode. The form of FIG. 20(a) is taken as a unit to connect the metal 1 and the metal 2 in series to integrate the left battery unit 4-1. Similarly, the form of FIG. 20(b) is taken as a unit to connect the metal 1 and the metal 2 in series to integrate the right battery unit 4-2.

In this embodiment, considering that a temperature difference between an external ambient temperature and a human body temperature cannot always be in the same situation, a circuit as shown in FIG. 21 is designed, where a left thermal-electrical conversion device is a simplification of the left battery unit 4-1, a right thermal-electrical conversion device is a simplification of the right battery unit 4-1, C refers to a power storage device, and R refers to a plurality of power consumption devices in the sensing module. The temperature switch A and the temperature switch B each have two temperature sensing probes 1 and 2, where 1 is to detect the external ambient temperature, and 2 is to detect the human body temperature. For the temperature switch A, when a temperature measured by A1 is greater than or equal to that measured by A2, A is switched off, and when the temperature measured by A1 is less than that measured by A2, A is switched on; for the temperature switch B, when a temperature measured by B1 is less than or equal to that measured by B2, B is switched off, and when the temperature measured by B1 is greater than that measured by B1, B is switched on. A left power supply is connected in series with the temperature switch A, and then connected in parallel with C and R; and a right power supply is connected in series with the temperature switch B, and then connected in parallel with C and R. According to the fact that the vest always needs to be in a working state and with reference to the actual ambient temperature and human body temperature, this circuit is explained in three situations:

(1) When the ambient temperature is greater than the human body temperature, A1 is greater than A2, and the temperature switch A is switched off. B1 is greater than B2, and the temperature switch B is switched on. The thermal-electrical conversion device in the right side works, which supplies energy to various electric devices in the vest on one hand, and stores energy for the electric storage device C on the other hand.

(2) When the ambient temperature is less than the human body temperature, A1 is less than A2, and the temperature switch A is switched on. B1 is less than B2, and the temperature switch B is switched off. The thermal-electrical conversion device in the left side works, which supplies energy to various electric devices in the vest and stores energy for the electric storage device C.

(3) When the ambient temperature is equal to the human body temperature, A1 is equal to A2, and the temperature switch A is switched off. B1 is equal to B2, and the temperature switch B is switched off. Neither the thermal-electrical conversion devices in the left or right side work, and the power storage device C supplies energy to various electric devices in the vest.

A voltage generated by the thermal-electrical conversion may be calculated by using the following formula:

U =S(T_h−T_c),

where U represents a thermoelectromotive force, S represents a sum of Seebeck coefficients of the two conductors, which is related to the material of the N-type semiconductor and the P-type semiconductor selected, T_hrepresents a temperature value of the high-temperature heat source, and T_crepresents a temperature value of the low-temperature heat source.

A total voltage of the integrated battery is:

U_total=nU,

where n is a quantity of (a) form or (b) form units in the integrated battery device. The difference between the ambient temperature and the human body temperature has little change. Therefore, this embodiment increases the quantity of n as much as possible to increase the total voltage U_totalof the integrated battery.

The left battery unit 4-1 and the right battery unit 4-2 may also adopt a dynamic-electrical conversion device to convert biological kinetic energy of the user into electrical energy. The device is mainly composed of a metallic coating on a flexible insulating pipe and a metallic coating on a flexible insulating pipe coated with treated polydimethylsiloxane. The metal coatings on the two flexible insulating pipes are used as two electrodes of the device respectively. Copper and gold with excellent conductivity may be used as the metal. Flexible insulating pipes are made of ethylene-vinyl acetate copolymer, or the like. The treated polydimethylsiloxane makes it easy for polydimethylsiloxane to absorb negative charges to pair that the two flexible insulating pipes. In order to clarify a working mechanism of the flexible insulating pipe, a working process may be simplified, and the two flexible insulating pipes move relatively, so that the metal electrode and the polydimethylsiloxane make a contact separation action. Based on a coupling effect of contact electrification and electrostatic induction, charge movement can be directly generated between the electrodes on the two flexible insulating pipes. The principle is as shown in FIG. 22:

In an original state (a), a surface of the polydimethylsiloxane is filled with negative electrostatic charges, and a metal electrode 1 generates positive charges. When the two flexible insulating pipes are pressed by external kinetic energy, a gap between a metal electrode 2 and the polydimethylsiloxane shrinks due to static induction, which leads to the accumulation of induced positive charges in the metal electrode 2, as shown in (b). Therefore, free electrons in the metal electrode 2 flow to the metal electrode 1 for electric field balance. An instantaneous positive current is produced during this process. It should be noted that the charges on the polydimethylsiloxane will not be destroyed even if the polydimethylsiloxane is contacted with the metal electrode 2, because the electrostatic charges naturally immerse into the insulator polydimethylsiloxane, as shown in (c). In the case that the two flexible insulating pipes are separated again, as shown in (d), the metal electrode 1 and the metal electrode 2 are restored to the original state (1). An instantaneous negative current may be generated. Therefore, during the contact separation process of the two flexible insulating pipes, the kinetic energy is converted into the electrical energy.

According to the characteristics of the current produced by the dynamic-electrical conversion device and the requirements of this embodiment, a circuit diagram as shown in FIG. 23 is designed. ZL is a rectifier, which aims to convert an alternating current produced by the dynamic-electrical conversion device into a direct current. B is a dynamic-electrical conversion device, C is an energy storing device, which can store electric energy, and R is various power consumption devices in the sensing module. S is a vibration sensing switch. The vibration sensing switch is provided with three switch connectors S1, S2, and S3. When user vibration is sensed by the vibration sensing switch, the switch connector Si is connected to the switch connector S2, and the switch connector S1 is connected to the switch connector S3. When there is no external vibration, the switch connector Si is disconnected from the switch connector S2, and the S1 switch connector is connected to the switch connector S3. According to the fact that this embodiment always needs to be in a working state and with reference to the actual situation of whether the user moves, this circuit is explained in two situations:

(1) When the user moves, the switch connector S1 on the vibration sensing switch is connected to the switch connector S2, and the switch connector S1 is connected to the switch connector S3. At this time, the dynamic-electrical conversion device converts kinetic energy into electrical energy to provide energy for R and stores the electric energy in the energy storage device C.

(2) When the user does not move, the switch connector Si on the vibration sensing switch is disconnected from the switch connector S2, and the switch connector Si is connected to the switch connector S3. At this time, the energy storing device C works to release the electrical energy stored therein to provide energy for R.

A structural form of the dynamic-electrical conversion device is as shown in FIG. 24. The flexible insulating pipe with the metal coating only is woven as one surface, and the flexible insulating pipe with metal coating covered by polydimethylsiloxane is woven as another surface. In view of that further expanding the contact between the two surfaces is beneficial for static induction, a knitting pattern is 5×5. The knitting pattern is sewed on the carrier of the embodiment.

A photovoltaic power storage in-situ integrated battery based on optical-electrical conversion is used in the wristband battery device 7-1 and the headband battery device 10-1.

The photovoltaic battery part may adopt:

(1) a silicon-based solar battery composed of a P-N junction formed by a silicon substrate doped with an n-type or p-type semiconductor; in the presence of sunlight illumination, the silicon substrate produces a photoelectric effect, and when the two ends are connected into a circuit, a current is produced;

(2) a sensitized solar battery composed of a conductive substrate, a semiconductor nano-porous film, a dye sensitizer, an electrolyte containing a redox couple, and a counter electrode; in the presence of sunlight illumination, dye molecules are excited from a ground state to an excited state, and electrons are injected into the semiconductor nano-porous film, the electrons may be quickly enriched on the conductive substrate, and flow to the counter electrode through an external conductor; and

(3) a formal perovskite solar battery composed of a conductive layer, an electron transport layer, a perovskite light-absorption layer, a hole transport layer, and an electrode, and a trans-perovskite solar battery composed of a conductive layer, a hole transport layer, a perovskite light-absorption layer, an electron transport layer, and an electrode. In the presence of sunlight illumination, a large quantity of electron-hole pairs may be generated in the perovskite light-absorption layer, where electrons and holes are respectively collected by the electron transport layer and the hole transport layer and transmitted to the electrode. When the two ends are connected into a circuit, a current may be generated.

A performance of the photovoltaic battery part may be calculated by the following formula:

E
_solar
=P
_in
·A
_solar
·t,

where E_solaris a photoelectric conversion power, t is a sunlight irradiation time, A_solaris a light-absorption area of the photovoltaic battery part, and P_inis an incident light power density, where an international standard is 100 mW/cm². The sunlight irradiation time depends on a plurality of factors, such as weather, outdoor time of the user, and the like. To improve the performance of the photovoltaic battery part, in this embodiment, the light-absorption area of the photovoltaic battery part is increased as much as possible.

A capacitor or a lithium battery may be used as the energy storage part for storing electric energy. A metal with a good conductivity may be used as the electrode.

In this embodiment, a circuit as shown in FIG. 25 is designed considering that this embodiment is always working regardless of the existence of sunshine in the external environment. R refers to various electrical devices in the sensing module, and G refers to a light sensing switch. The light sensing switch is provided with three switch connectors a, b, and c. The switch connector a is connected to the switch connector c when there is light outside, and the switch connector a is connected to the switch connector b when there is no light outside. a is connected in series with R through a wireway, and R is connected to a base layer/electrode through a wireway. b is connected in series with a transition electrode through a wireway, and c is connected to the base layer/electrode through a wireway. According to the variable of sunlight, this circuit is explained in two situations:

(1) when there is sunlight in the daytime, the switch connector a on the light sensing switch is connected to the switch connector c. At this time, the photovoltaic battery part works, which converts light energy into electrical energy to provide energy for R, and stores the electric energy in the energy storage device C.

(2) when there is no sunlight at night, the switch connector a on the light sensing switch is connected to the switch connector b. At this time, the energy storage part works to release the electrical energy stored therein to provide energy for R.

The left battery device 4-1 and the right battery device 4-2 are connected to the transformer through conductors to change the voltages, and then, respectively connected to the shell temperature band 3-1, the chest breathing band 3-2, the abdominal breathing band 3-3, the heart rate ECG band 3-4, and the vest main control chip 2-15 through the conductors to convey electric energy.

For the wristband, the wristband body 5-1 is internally provided with conductors. The blood flow rate band 6-1, the blood glucose band 6-2, and the wristband main control chip 5-3 are connected by the connectors to transmit physical sign parameter signals of the user measured by the blood flow rate band 6-1 and the blood glucose band 6-2 to the wristband main control chip 5-3.

Information transmission and information processing and feedback modules include mobile phone terminals, various databases and institutional facilities. As one of the necessary communication tools in modern life, the mobile phone has very powerful functions in processing, storing and transmitting data. In this embodiment, the mobile phone terminal serves as a transfer station for storing and sending data, and also analyzes and processes the stored data and gives an alarm for abnormal data. The various databases and institutional facilities include large databases, sub-health and disease databases, disease control centers, pharmaceutical institutions and hospital institutions.

Through analysis and processing, a health status of the user is sent to the mobile phone terminal in a form to give the user feedback. In addition, the alarm of the mobile phone terminal is handled urgently.

The vest main control chip 2-15, the wristband main control chip 5-3 and the headband main control chip 7-3 in the information collection module are used for collecting and storing the data transmitted by the shell temperature band 3-1, the chest breathing band 3-2, the abdominal breathing band 3-3, the heart rate ECG band 3-4, the blood flow rate band 6-1, the blood glucose band 6-2, the blood oxygen band 9-1 and the deep temperature band 9-2, and transmitting the collected information about the physical sign parameters of the user to the mobile phone via Bluetooth for subsequent analysis and feedback process.

The framework of information transmission, information processing and feedback is as shown in FIG. 27. The collected personal information and physical sign parameters of the user may be analyzed and processed in five levels in the whole transmission process, a report is generated from results and sent to the mobile phone for feedback, and the user is arranged for relevant treatment according to the results. The whole process is established based on the internet. The whole process is described hereinafter according to FIG. 27.

The user enters personal information (such as a gender, a race, an age, and the like) into the mobile phone first, and the master control chip may continuously transmit the collected information about the physical sign parameters of the user to the mobile phone via Bluetooth. A preset health threshold of people is set in advance in the mobile phone, and the mobile phone may analyze and process the collected information in a first level.
