Embodiments of the present disclosure relate generally to methods and systems for collecting biometric information and more particularly to wearable dry electrodes for collecting biometric information.
Sensing of vital signs, e.g., heart rate, respiration, temperature, etc., and electromyography, i.e., measurement of muscular activity, and other biometric monitoring are important in a variety of applications ranging from health monitoring of medical patients to performance monitoring of athletes and a combination of performance and health monitoring of military personnel, astronauts, etc. Typically, sensors for performing such monitoring are applied to the monitored person individually at various locations depending on the information monitored. This can be time consuming and tedious if measuring multiple different biometric information. Additionally, such sensors are prone to slippage or dislocation, are susceptible to contamination by dirt and moisture, and may be limiting of the motion of the wearer when the wearer is active. Hence, there is a need in the art for improved systems and methods for collecting biometric information.
Embodiments of the disclosure provide systems and methods for wearable dry electrodes for collecting biometric information. According to one embodiment, a dry electrode bio-sensor can comprise one or more conductive pads comprising electrodes of the dry electrode bio-sensor and one or more connectivity traces coupled with each of the one or more conductive pads. The connectivity traces can provide electrical connections for one or more of power to the one or more conductive pads or signals comprising biometric information from the one or more conductive pads. A backing can be coupled with and can retain the one or more conductive pads and the one or more connectivity traces. The dry electrode bio-sensor can comprise an electrocardiography (ECG) sensor, a respiration sensor, a PhotoPlethysmoGram (PPG) sensor, a temperature sensor, an electromyography (EMG) sensor, or another biometric sensor.
The one or more conductive pads and the one or more connectivity traces can be printed in stretchable and washable conductive ink. In some cases, the one or more conductive pads and one or more connectivity traces can be printed on a stretchable and washable substrate. A surface of each of the one or more conductive pads placed against a wearer's skin when the dry electrode bio-sensor is in use can be textured.
A standoff can be disposed on a side of the backing opposite from the one or more conductive pads, the standoff transferring pressure to the one or more conductive pads when the conductive pads are applied to a skin of a wearer of the dry-electrode bio-sensor. The standoff can be constructed of a flexible material. The pressure transferred by the standoff to the one or more conductive pads can be applied by a compressive textile. The shape of the standoff on a portion adjacent to the compressive textile can have a more curvature than a portion adjacent to the one or more conductive pads.
A bio-sensing garment for collecting biometric information from a wearer of the garment, the garment comprising a fabric layer forming the garment and a plurality of dry electrode bio-sensors integrated into the fabric layer. Each dry-electrode bio-sensor can comprise one or more conductive pads comprising electrodes of the dry electrode bio-sensor, one or more connectivity traces coupled with each of the one or more conductive pads, the connectivity traces providing electrical connections for one or more of power to the one or more conductive pads or signals comprising biometric information from the one or more conductive pads, and a backing coupled with and retaining the one or more conductive pads and the one or more connectivity traces. A connectivity layer can be integrated into the fabric layer and can comprise one or more signal conductors coupled with one or more of the connectivity traces of each dry electrode bio-sensors and one or more power conductors coupled with one or more of the connectivity traces of each dry electrode bio-sensors. A power source can be coupled with each of the power conductors and can provide, via the power conductors of the connectivity layer, electrical power to each of the plurality of dry electrode bio-sensors. A signal monitor can be coupled with the connectivity layer and can receive, via the signal conductors of the connectivity layer, a signal comprising biometric information from each of the plurality of dry electrode bio-sensors. A gateway can be coupled with the signal monitor. The gateway can receive the biometric information from the signal monitor and providing the biometric information to an external computer system.
The one or more conductive pads and the one or more connectivity traces of the dry electrode bio-sensors can be printed in stretchable and washable conductive ink. In some cases, the one or more conductive pads and one or more connectivity traces can be printed on a stretchable and washable substrate. A surface of each of the one or more conductive pads placed against a wearer's skin when the dry electrode bio-sensor is in use can be textured. A standoff can be disposed on a side of the backing opposite from the one or more conductive pads. The standoff can transfer pressure to the one or more conductive pads when the conductive pads are applied to a skin of a wearer of the dry-electrode bio-sensor. The standoff can be constructed of a flexible material and the pressure transferred by the standoff to the one or more conductive pads can be applied by the fabric layer. A shape of the standoff on a portion adjacent to the compressive textile can have a more curvature than a portion adjacent to the one or more conductive pads.

Embodiments of the disclosure provide systems and methods for a garment including integrated sensors for collecting biometric information. Generally speaking and as will be described in greater detail below, to monitor health and muscular activities, a garment equipped with bio-sensors could be worn by a person whose health requires a continuous monitoring. Such garment could be equipped with bio-sensors that monitors vital signals such as ECG, respiration, PPG, blood pressure, core body temperature, as well as muscular activities like EMG. These sensors can be located within the garment and on the body of the wearer of the garment to monitor electrical signals as well as by other sensing means like optically or thermally. The signals generated by these sensors can be gathered and processed by electronic circuits that are interconnected via a web of connectivity layer integrated in the garment. These interconnected sensors and circuits can be so integrated into the garment that the interference with the person's normal activities is minimal. Electrical power for the bio-sensing system could be provided by a portable source within, on, or near the garment or by using energy harvesting means similarly situated within, on, or near the garment. The monitoring data can be transmitted on wire or wireless communications connection to a computing node for further analysis and alarm generation as appropriate.
The electronic circuits for the sensors 110A-110I can be interconnected via the connectivity layer (not shown here) which can comprise a web of traces printed on a stretchable and bio-compatible substrate, such as TPU, using conductive ink. This substrate can be bound to the fabric layer of the bio-sensing integrated garment 100. These traces could be made in different conductive ink with different geometries including straight shapes as well as meander shapes so as to achieve the minimum resistance under stretch conduction while maintaining the smallest dimensions. Some of these traces can constitute power lines that provide electrical power to the bio-sensing electronics dispersed all over the garment. In order to mitigate the excessive path resistance, increase due to stretching, the signal monitor 125 may boost the voltage from one bio-sensing node to the other. The boosting is decided by software based on need; i.e. whether the voltage has gone below a threshold. These webs of connectivity can carry high speed digital signals implementing a communication protocol for handling the data transport from the data collection sites, i.e., the electronic circuits of the sensors, to a gateway that funnel all the data stream to the external data analysis compute system outside the garment. The gateway could be connecting to the outside compute system via wire or wireless means.
The integration of the sensor 200 with the garment can be carried out in way that the connection between the printed circuit board 225 pinout and the printed connectivity traces on the TPU web 235 can be realized by a mechanical clamping of the inner housing 205, PET stiffener 220, and outer housing 250 as well as other means such as by using conductive adhesive. The integration of the sensor 200 into the garment in this way, together with the inner seal gasket 210 and outer seal gasket 245 provides a tight seal so as to prevent any water or contaminant leakage.
The connectivity layer 115 can comprise one or more signal conductors 515A coupled with each of the plurality of biometric sensors 110A-110D and one or more power conductors 515B coupled with each of the plurality of biometric sensors. The connectivity layer 115 can further comprise a flexible and stretchable substrate of the garment and the signal conductors 515A and power conductors 515B of the connectivity layer 115 can comprise a plurality of traces of conductive ink printed on the flexible and stretchable substrate. The plurality of traces can comprise one or more straight-shaped traces and one or more meander-shaped traces. Each sensor of the plurality of biometric sensors 110A-110D can be integrated into the garment 100 and can be connected with the connectivity layer 115 by mechanical clamping and/or the use of a conductive adhesive.
The garment 100 can further comprise a power source 510 coupled with each of the power conductors 515B and providing, via the power conductors 515B of the connectivity layer 115, electrical power to each of the plurality of biometric sensors 110A-110D. A signal monitor 125 can be coupled with the connectivity layer 115 and can receive, via the signal conductors 515A of the connectivity layer 115, a signal comprising biometric information from each of the plurality of biometric sensors 110A-110D. A gateway 505 can be coupled with the signal monitor 125. The gateway 505 can receive the biometric information from the signal monitor 125 and provide the biometric information to an external computer system. The signal monitor 125 can also be coupled with the power source 510. In some cases, the signal monitor 125 can compare each received signal comprising biometric information from each of the plurality of biometric sensors 110A-110D to a threshold value corresponding to each sensor. In response to a signal being below the threshold value for the corresponding sensor, a voltage supplied to the corresponding sensor by the power source can be increased.
As described above, the biometric information can be received via a connectivity layer 115 integrated into the fabric layer 105 of the garment 100 and comprising one or more signal conductors 515A coupled with each of the plurality of biometric sensors 110A-110I and one or more power conductors 515B coupled with each of the plurality of biometric sensors 110A-110I. The signal monitor 125 can include one or more communication interfaces 620 providing a connection to the signal conductors 515A of the connectivity layer 115 to allow the processor 605 to receive the biometric information from the plurality of biometric sensors 110A-110I.
The memory 610 can also store a set of uploading instructions 630 which, when executed by the processor 605, can further cause the processor 605 of the signal monitor 125 to provide the received biometric information to an external computer system via a gateway 505 of the bio-sensing garment 100 as described above. In some cases, the memory 610 may also store a set of power adjustment instructions 635 which, when executed by the processor 605, can further cause the processor 605 of the signal monitor 125 to compare each received voltage on the power traces to a threshold value corresponding to each sensor. In response to a voltage being below the threshold value for the corresponding sensor, the power adjustment instructions 635 can cause the processor 605 of the signal monitor 125 to increase a voltage supplied to the corresponding sensor by the power source 510.
In some cases, each received voltage on the power traces can be compared 710 to a threshold value corresponding to each sensor and a determination 715 can be made as to whether the received voltage is below the threshold. In response to determining 715 a signal being below the threshold value for the corresponding sensor, a voltage supplied to the corresponding sensor by a power source of the bio-sensing garment can be increased 720. The received biometric information can then be provided 725 by the signal monitor of the bio-sensing garment to an external computer system via a gateway of the bio-sensing garment.
To monitor health and muscular activities, a garment 100 such as described herein equipped with bio-sensors 110A-110I could be worn by a person whose health requires a continuous monitoring. Such garment could employ electrodes to track heart, respiration as well as muscular activities. These electrodes should be textile-integratable, capable of reliably picking up the vital or EMG signals from the body, motion-resistant, cleanable, scalable, soft, unperceivable, and minimally interfering with the user's normal activities. The traditional wet-electrodes are not suitable to garment integration as they do not fulfil the above requirements. According to one embodiment, bio-sensors 110A-110I for integration into a garment 100 as described herein can comprise a dry electrode sensor consisting of a conductive pad area, connectivity traces, and a backing.
Regardless of the exact configuration, both the conductive pad area and the connectivity traces can be printed using conductive ink, which is stretchable and washable. The printing can be performed over a substrate that is stretchable and washable such as TPU. To enhance the contact with the skin, the printing of the conductive pad could be textured in different patterns.
The one or more conductive pads 905 and the one or more connectivity traces 845A and 845B can be printed in stretchable and washable conductive ink. In some cases, the one or more conductive pads 905 and one or more connectivity traces 845A and 845B can be printed on a stretchable and washable substrate. A surface of each of the one or more conductive pads placed against a wearer's skin 920 when the dry electrode bio-sensor 830 is in use can be textured.
A standoff 915 can be disposed on a side of the backing 910 opposite from the one or more conductive pads 905, the standoff 915 transferring pressure to the one or more conductive pads 905 when the conductive pads 905 are applied to a skin 920 of a wearer of the dry-electrode bio-sensor 830. The standoff 915 can be constructed of a flexible material. The pressure transferred by the standoff 915 to the one or more conductive pads 905 can be applied by a compressive textile, e.g., the fabric layer 105 of the garment 100. The shape of the standoff 915 on a portion adjacent to the compressive textile can have a more curvature than a portion adjacent to the one or more conductive pads 905.
Thus, the electrode has a conductive pad 905 area that interfaces with the skin 920 from which the bio signals are picked up. Note that the conduction pad 905 could be printed on a lamination layer that adheres to the fabric as well as to the standoff 915. The performance of the signal pick-up is a function of the compression exerted on the conductive pad 905 against the skin 920, i.e., the higher the compression the better the signal pick-up. The compression can be attained by having a compressive textile pushing down on the electrode back, i.e., the standoff 915. The compression value applied by the fabric layer 105 is function of the standoff 915 shape.
According to one embodiment, the construction of the standoff 905 could be based on foamy, flexible or rigid materials so as to comply to the skin curvature and thus to provide a more reliable skin contact. The pressure on the conductive pads 905 emanates from the use of compressive textile the wraps around the body part and carries the electrodes. The pressure can be increased by shaping the back of the standoff 915, i.e., the sides that faces the compressive fabric layer 105, so that its curvature is a lot smaller than the body curvature where the electrode is located. The law that governs that the pressure is Laplace's law:
Where P1 is the pressure applied on the back of the standoff, R is the radius of the curvature of the standoff, T is the tension (N/cm) from the textile due to stretching defined as:
Where F is the force applied to a reference sample of width W (cm) that stretched ε0 (mm), and ε (mm) is the stretch of the garment wrapped around a part of the body (like arm, leg, or torso).
Also, the area reduction of the area of the back of the standoff with respect to the area of the conductive pad:
