The present invention relates to a posture monitoring device and a method and a system for monitoring a posture using the same, and more particularly, to a posture monitoring device for measuring and correcting a user's posture by utilizing a resistance element which is elastic and has a resistance which is changed according to mechanical strain, and a method and a system for monitoring a posture using the same.
With the development of computer science and the development of the economy, as the working and academic environment is changed, the sedentary time rather than dynamic physical activity has been rapidly increased. In such an environment, when an incorrect posture is maintained for a long time, fatigue is easily felt, and particularly, backache and cervical pain are easily caused.
Pain in the lumbar and cervical spinal column is a major spinal disease that 80% or higher of the total population experiences by various causes and is caused by an incorrect posture as well as the cause of spinal injury.
Until the curvature of the spinal column is severely worsened, the curvature of the spinal column may be sufficiently alleviated and improved only by treatment with correct posture and correct habits, rather than recovery through direct treatment. Recently, the development of a posture monitoring system capable of measuring and correcting the posture has been actively performed.
For example, there are proposed a system for monitoring a sitting posture in real time by attaching a pressure sensor to a chair to sense the pressure applied to the chair by a body (see Prior Art 1), a system for monitoring a posture based on a captured image by attaching a camera to a display device such as a monitor to capture a user's posture (see Prior Art 2), and a system for monitoring a posture by wearing clothes with an EMG sensor, an inertial sensor, etc. and analyzing a signal sensed from various sensors (see Prior Art 3).
However, such a conventional system requires a separate sensing means such as a chair with a sensor, a photographing device such as a camera, and clothes equipped with a sensor to determine a user's posture. In the case of Prior Arts 1 and 2, there is a limitation that it may only be used under quite limited conditions in that it is possible to monitor the posture only when the user takes a sitting position at a specific position. In the case of Prior Art 3, there is an inconvenience to the user's activities in terms of attaching various sensors to the body, acquisition of measurement information or a processing algorithm is complicated, and it is difficult to accurately determine the user's posture in real time.
The present invention is derived to solve the problems above and directed to providing a posture measuring and correcting device including elastic resistance elements which are attached onto or inserted into the body of a user so that the resistance is sensitively changed according to mechanical strain depending on a user's posture, and a monitoring method and system utilizing the same.
Further, the present invention is directed to providing a posture monitoring device configured to be easily portable and be used in everyday life without spatial constraints as compared with a conventional posture monitoring device by using the posture monitoring device of the present invention by the user.
Further, the present invention is directed to providing a posture monitoring device, method, and system configured to check posture information in real time and correct the posture by interlocking a terminal such as a smart phone with a monitoring device provided in the body of the user.

First, a posture monitoring device of the present invention will be described in detail with reference to
Referring to
The first elastic resistance element 110 and the second elastic resistance element 120 are elements which are configured to measure the degree of stretching of a first part 11 and a second part 12 on a dorsal part, which are divided by the spinal column of the body. The first elastic resistance element 110 and the second elastic resistance element 120 are made of conductive materials to have elasticity and have a characteristic in which the resistance is sensitively changed according to mechanical strain depending on a user's posture.
Here, the dorsal part means the neck, the back, the waist of the back of the spinal column, and for convenience of description, the exemplary embodiment illustrates that the elastic resistance elements 110 and 120 are disposed on the back part, but is not limited thereto.
In this case, as illustrated in
At this time, the first elastic resistance element 110 and the second elastic resistance element 120 may be configured to be attached onto skins of the first part 11 and the second part 12 or to be inserted into the skins, respectively.
For example, the first elastic resistance element 110 and the second elastic resistance element 120 may be resistance elements manufactured in various structures in a film form and a three-dimensional form through a combination of a stretchable elastic material and conductive nanoparticles. The elastic material may be polydimethyl siloxane (PDMS), which is a kind of silicone rubber having elasticity and flexibility, and the conductive nanoparticles may be carbon particles. In addition, the conductive nanoparticles may be nanomaterials having high conductivity, such as carbon nanotubes, graphene, metal nanowires, and metal nanoparticles. At this time, it is preferable that the materials forming the first elastic resistance element 110 and the second elastic resistance element 120 are adopted as a material having a small change in specific resistance due to external influences (temperature, humidity, etc.).
Meanwhile, the first elastic resistance element 110 and the second elastic resistance element 120 may also be formed in the form in which an electronic ink (E-ink) containing conductive nanoparticles and manufactured to be applied to the skin is applied to the skin or inserted into the skin (e.g., tattoo). Such an E-ink may employ a configuration of conductive ink that is safe for the skin disclosed in Korean Patent Publication No. 10-2011-0133556.
When the E-ink is applied to the skin or inserted into the skin to form the first elastic resistance element 110 and the second elastic resistance element 120, the E-ink is preferably made of a material that can be combined with living tissue, is a soft and elastic material, and is harmless to the human body. In addition, when a current flowing in the first elastic resistance element 110 and the second elastic resistance element 120 may cause a direct effect (e.g., electric shock) on the tissue, it is preferable that an insulating layer is formed between the first elastic resistance element 110 and the second elastic resistance element 120 and the skin or subcutaneous tissue.
The insulating layer may also be formed to surround the first elastic resistance element 110 and the second elastic resistance element 120, or may also be formed in the form of a film in contact with the skin or subcutaneous tissue. In addition to the illustrated shapes, of course, the insulating layer may be formed to protect the skin or subcutaneous tissue in various ways. At this time, it is preferable that the insulating layer is formed of a material having the same or similar elasticity as or to that of the elastic resistance elements 110 and 120.
In addition, the first elastic resistance element 110 and the second elastic resistance element 120 may be applied in various forms (e.g., a film form, etc.) in which the resistance is sensitively changed according to mechanical strain, and of course, a technique known as a flexible tactile material capable of sensing changes in the body such as pressure and strain may be applied to the present invention.
The power supply device 130 applies a voltage or current to the first elastic resistance element 110 and the second elastic resistance element 120 by the electrodes 111 and 112.
When the voltage or current is applied to the first elastic resistance element 110 and the second elastic resistance element 120 by the power supply device 130, the resistance measuring device 140 may measure the current or voltage flowing in the first elastic resistance element 110 and the second elastic resistance element 120 to calculate the resistances of the first elastic resistance element 110 and the second elastic resistance element 120.
The displacement of the calculated resistances of the first elastic resistance element 110 and the second elastic resistance element 120 or the changed resistances is used for calculating information about mechanical strain occurring in the first elastic resistance element 110 and the second elastic resistance element 120 and information about the curvatures of the body in the first part 11 and the second part 12. This will be described below with reference to
The communication module 150 transmits data output from the resistance measuring device 140, that is, data about at least one of resistance, current, and voltage, to an external device.
The communication module 150 is preferably a Bluetooth module. However, the present invention is not limited thereto, and of course, the communication module 150 may be a near field communication module such as radio frequency identification (RFID), infrared data association (IrDA), ZigBee, and Wi-Fi Direct, and any known network may be used.
Meanwhile, a plurality of first elastic resistance elements 110 and second elastic resistance elements 120 may be provided. As illustrated in
In this case, the resistance measuring device 140 may calculate an average value of data output from the first elastic resistance elements 110 and the second elastic resistance elements 120 to provide the average value to the communication module 150. Each data output from the first elastic resistance elements 110 and the second elastic resistance elements 120 may also be provided to the communication module 150 without a separate operation.
Furthermore, the posture monitoring device 100 of the present invention further includes a first stimulating element 160 and a second stimulating element 170 which are attached onto the skins of the first part 11 and the second part 12 or inserted to be located inside the skins.
The first stimulating element 160 and the second stimulating element 170 are configured to apply stimulation to the skins or muscles of the first part 11 and the second part 12. For example, the first stimulating element 160 and the second stimulating element 170 may be elements configured to apply stimulation to the user's skin or muscle in the same manner as electrical muscle stimulation or transcutaneous electrical nerve stimulation. In this case, the stimulation applied by the first stimulating element 160 and the second stimulating element 170 may be an electrical stimulation signal, and in addition, may also be a vibration stimulation signal.
The first stimulating element 160 and the second stimulating element 170 may be configured to operate upon receiving a stimulation signal from the communication module 150, and the operation of the first stimulating element 160 and the second stimulating element 170 will be described below with reference to
As illustrated in
However, the arrangement manner of the first stimulating element 160 and the second stimulating element 170 is not limited to the illustrated, and so long as the stimulation may be applied to the first part 11 and the second part 12, of course, the first stimulating element 160 and the second stimulating element 170 may be arranged in various structures.
Meanwhile, referring to
The third elastic resistance element 180 is also configured to be attached onto the skin or inserted into the skin like the first elastic resistance element 110 and the second elastic resistance element 120, and may be disposed to measure the degree of stretching of the skin of the third part 13. However, unlike the first elastic resistance element 110 and the second elastic resistance element 120, the third elastic resistance element 180 may be disposed to measure the degree of stretching of the skin in a direction perpendicular to the longitudinal direction of the spinal column.
The posture monitoring device 100′ further includes the third elastic resistance element 180 in the third part 13 to have an advantage of more precisely monitoring various postures by measuring the stretching of the skins of the first part 11, the second part 12, and the third part 13.
Further, referring to
The fourth elastic resistance element 180′ is also configured to be attached onto the skin or inserted into the skin like the first elastic resistance element 110 and the second elastic resistance element 120, and may be disposed to measure the degree of stretching of the skin of the fourth part 14. However, unlike the third elastic resistance element 180, the fourth elastic resistance element 180′ may be disposed to measure the degree of stretching of the skin in a direction parallel to the longitudinal direction of the spinal column.
The posture monitoring device 100″ further includes the fourth elastic resistance element 180′ in the fourth part 14 to have an advantage of more precisely monitoring various postures by measuring the stretching of the skins of the first part 11, the second part 12, and the fourth part 14.
Meanwhile, in
Since a driving principle of the third elastic resistance element 180 and the fourth elastic resistance element 180′ is the same as that of the first elastic resistance element 110 and the second elastic resistance element 120, a duplicated description will be omitted.
In addition, the posture monitoring devices 100′ and 100″ of the present invention may further include a third stimulating element 190 or fourth stimulating element 190′ configured to apply stimulation to the skin or muscle in the third part 13 or the fourth part 14 which is distinguished from the first part 11 and the second part 12. The third stimulating element 190 and the fourth stimulating element 190′ may be included in the posture monitoring device of the present invention in addition to the first stimulating element 160 and the second stimulating element 170, and are preferably disposed to correct a posture of the shoulder or neck portion of the user.
Since a driving principle of the third stimulating element 190 and the fourth stimulating element 190′ is the same as that of the first stimulating element 160 and the second stimulating element 170, a duplicated description will be omitted.
Meanwhile, as illustrated in
Hereinafter, a method and a system for monitoring a posture of the present invention will be described in detail with reference to
Referring to
The controller 200 processes various data for performing the posture monitoring method of the present invention.
Specifically, the controller 200 receives data output from the first elastic resistance element 110 and the second elastic resistance element 120 of the posture monitoring device 100 to determine the degree of stretching of the first part 11 and the second part 12 on a dorsal part and determine the degree of curvature of the body and the posture based on the determined degree of stretching. In addition, when the determined degree of curvature of the body is greater than or equal to a preset threshold, the controller 200 may provide a stimulation signal to the first stimulating element 160 and the second stimulating element 170 to correct the user's posture.
The controller 200 may correspond to at least one processor or may include at least one processor.
In addition, the controller 200 may be implemented as a separate device and driven as illustrated in the drawing, or may be driven in a form included in another hardware device (e.g., the user terminal 300) such as a microprocessor or a general purpose computer system. Hereinafter, the controller 200 may be implemented as a separate device to perform the posture monitoring method of the present invention, but the present invention is not limited thereto.
The user terminal 300 may be a communication terminal capable of using a web or mobile service in a wired or wireless communication environment. Specifically, the user terminal 300 may be a device or a terminal including a processor, a storage unit, a communication module, and may be a general purpose computer, a special purpose computer, a mobile terminal such as a smart phone, a desktop or laptop computer, or an accessory device used in combination with them. The user terminal 300 may include a display unit that displays a screen and an input device that receives data from a user.
The user terminal 300 may communicate with the controller 200 and share posture information of the user measured by the posture monitoring device 100, and may also transmit a signal input to the user terminal 300 to the posture monitoring device 100 through the controller 200.
Hereinafter, for convenience of description, it is assumed that the user terminal 300 is a smart phone equipped with an application related to the posture monitoring method of the present invention, but the present invention is not limited thereto, and of course, the user terminal 300 may be one of the terminals listed above.
Hereinafter, a method of performing the posture monitoring method of the present invention by the controller 200 will be described with reference to
The controller 200 receives data output from the first elastic resistance element 110 and the second elastic resistance element 120 from the communication module 150 of the posture monitoring device 100 (S10).
Here, the data is data relating to the current, voltage, and resistance of the first elastic resistance element 110 and the second elastic resistance element 120.
The controller 200 calculates information on mechanical strain generated in the first elastic resistance element 110 and the second elastic resistance element 120 based on the received data (S20), and determines the user's posture by measuring the degree of curvature of the body in the first part and the second part based on the calculated information on mechanical strain (S30).
A principle is as follows in which the controller 200 calculates the information on mechanical strain generated in the first elastic resistance element 110 and the second elastic resistance element 120 through the data output from the first elastic resistance element 110 and the second elastic resistance element 120 and determines the user's posture by measuring the degree of stretching of the first part 11 and the second part 12 of the dorsal part and the degree of curvature of the body.
When the first part 11 and the second part 12 of the dorsal part are stretched, the lengths of the first elastic resistance element 110 and the second elastic resistance element 120 are increased, but the thicknesses of the first elastic resistance element 110 and the second elastic resistance element 120 are decreased. At this time, the resistances of the first elastic resistance element 110 and the second elastic resistance element 120 are increased. On the contrary, when the first part 11 and the second part 12 of the dorsal part are contracted, the lengths of the first elastic resistance element 110 and the second elastic resistance element 120 are decreased, but the thicknesses of the first elastic resistance element 110 and the second elastic resistance element 120 are increased. At this time, the resistances of the first elastic resistance element 110 and the second elastic resistance element 120 are decreased.
In this principle, the controller 200 calculates changes in resistances of the first elastic resistance element 110 and the second elastic resistance element 120 to measure the degree of stretching of the first part 11 and the second part 12 of the dorsal part in which the first elastic resistance element 110 and the second elastic resistance element 120 are disposed.
For example, if the resistance of the first elastic resistance element 110 is increased and the resistance of the second elastic resistance element 120 is increased, both the first part 11 and the second part 12 of the dorsal part are stretched, and thus, the controller 200 determines the user's posture as a posture of bending the back or waist or lowering the head.
On the contrary, if the resistance of the first elastic resistance element 110 is decreased and the resistance of the second elastic resistance element 120 is decreased, both the first part 11 and the second part 12 of the dorsal part are contracted, and thus, the controller 200 determines the user's posture as a posture of bending back the back or waist or raising the head.
Meanwhile, if the resistance of the first elastic resistance element 110 is decreased and the resistance of the second elastic resistance element 120 is increased, or the resistance of the first elastic resistance element 110 is increased and the resistance of the second elastic resistance element 120 is decreased, one of the first part 11 and the second part 12 of the dorsal part is stretched and the other part is contracted, and thus, the controller 200 determines the user's posture as being inclined to the left or right or rotating the trunk.
Next, the controller 200 determines whether the degree of curvature of the body in the first part 11 and the second part 12 is equal to or greater than a preset threshold (S40).
When the degree of curvature of the body is equal to or greater than the preset threshold, it means that the user takes an incorrect posture, that is, an improper posture at the time of measuring.
Here, the preset threshold may be appropriately set for the user who uses the posture monitoring device 100 of the present invention and preset in the controller 200.
For example, while the user naturally sits or stands (standing position), a setting point is set, and the degree of curvature of the body is measured by setting intentionally each part of the body by flexion, extension, lateral rotation, and lateral bending. In this case, a technique such as radiographic imaging may be utilized. Between the standing position of the user and the position where the body is strained to the maximum value, the degree of deviating from the standing position at a predetermined ratio may be determined as the preset threshold.
At this time, the controller 200 may record a time that the degree of curvature of the body lasts at the preset threshold or higher to make a database for giving feedback to the user, and transmit the recorded time to the user terminal 300 to make it for the user to check the monitoring content for the own posture.
Next, when the controller 200 determines whether the degree of curvature of the user's body is equal to or greater than the preset threshold, the controller 200 transmits a signal so that at least one of the first stimulating element 160 and the second stimulating element 170 applies stimulation to the skin or muscle (S50).
For example, on the other hand, when the controller 200 determines that the second part 12 of the dorsal part is stretched by the preset threshold or higher by decreasing the resistance of the first elastic resistance element 110 and increasing the resistance of the second elastic resistance element 120, the controller 200 may transmit a signal to the second stimulating element 170 to apply stimulation to the skin or muscle.
Through this feedback process, the muscle on the side applied with the stimulation may be contracted, and at the same time, the user may sense the stimulation to correct the posture.
On the other hand, when the controller 200 determines whether the degree of curvature of the user's body is equal to or greater than the preset threshold, the controller 200 may transmit an alarm signal to the user terminal 300. When the alarm signal is transmitted to the user terminal 300 as sound, vibration, or visual information, the user may also sense the stimulation to correct the posture.
According to the posture monitoring device, method, and system of the present invention, when the user maintains an improper posture for a predetermined time or higher, a signal to correct the posture is transmitted to the user, thereby preventing diseases such as discopathy (disc disease) of the spinal column or cyphosis and scoliosis caused by the improper posture. Further, by inducing patients having surgery due to a spinal lesion and required to maintain a correct posture for a certain period of time to maintain the correct posture, it is possible to prevent postoperative complications.
Hereinabove, the exemplary embodiments of the present invention have been described with the accompanying drawings, but it can be understood by those skilled in the art that the present invention can be executed in other detailed forms without changing the technical spirit or requisite features of the present invention. Therefore, it should be appreciated that the aforementioned exemplary embodiments described above are all illustrative in all aspects and are not restricted.
