For example, the first strain gauge 632a may output a first sensing value via the first metal wire 632b and output a second sensing value for correcting the first sensing value through the second metal wire 634b.
For example, a metal strain gauge may have a resistance characteristic that resistance linearly increases as a temperature rises. Accordingly, the monitoring server includes a module or algorithm for correcting the sensing value, and the monitoring server may correct an error of the sensing value by a temperature difference between the sensor modules by using the first sensing value output from the driving sensor module and the second sensing value output from the correction sensor module.

In an embodiment, lengths of line widths and lengths of gaps between lines of the strain gauges 632a and 636a of the driving sensor module and the strain gauges 634a and 638a of the correction sensor module may be different from each other. The length of the line width and the length of the gap between the lines may be implemented to be different according to an application target of the sensor or a main measurement direction of the force.
For example, a width of lines (line patterns) of the strain gauges 632a and 636a of the driving sensor module may be in a range of 40 μm to 90 μm, a gap between two immediately neighboring lines (line patterns) may be in a range of 110 μm to 160 μm, a width of lines of the strain gauges 634a and 638a of the correction sensor module may be in a range of 50 μm to 100 μm, a gap between the two immediately neighboring lines may be 100 μm to 150 μm.

In an embodiment, the expected folding line or bending line of the flexible tactile sensor is assumed by a designer in advance by considering an application target, an application location, or force to be measured and the strain gauges 632a, 634a, 636a, and 638a may be formed based on the assumption.

In an embodiment, the first strain gauge 632a and the third strain gauge 636a may be formed at opposite locations corresponding to each other and the second strain gauge 634a and the fourth strain gauge 638a may be formed at opposite locations corresponding to each other. In another embodiment, the first strain gauge 632a and the second strain gauge 634a at one side and the third strain gauge 636a and the fourth strain gauge 638a may be formed to cross each other (to have different orientations when viewed in a direction perpendicular to a major surface of the polymer layer). For example, the first strain gauge 632a, the third strain gauge 636a, the second strain gauge 634a, and the fourth strain gauge 638a may be formed to cross each other in order.
In the flexible tactile sensor configured as above, the sensors are provided on both surfaces to accurately sense the force on both surfaces.

For example, the monitoring server 140 may monitor the degree of improvement of the muscular movement of the user 110 or the bending (e.g., the bending angle, the bending direction, etc.) of the joint depending on the remedial exercise. The monitoring server 140 compares a past analysis result (or sensing value) of the user 110 with a current analysis result (or sensing value) to analyze the degree of improvement of the movement of the muscle or a functional improvement degree of the joint and monitor an effect of the remedial exercise.
In an embodiment, when the user movement monitoring system is used to monitor training of the user, the monitoring server 140 may monitor a training result of the user 110 based on the received sensing value. For example, the monitoring server 140 may monitor 140 may compare a reference posture of the training exercise and a posture of the user 110 depending on the movement of muscle or the bending (e.g., the bending angle, the bending direction, etc.) of the joint of the user 110 and monitor a comparison result. For example, the monitoring server 140 compares and analyzes a past analysis result (or sensing value) of the user 110 with a current analysis result (or sensing value) to monitor the degree of accuracy improvement of the posture and the effect of the training.
The monitoring server 140 may provide the monitoring result information to the user terminal or the medical team terminal (step S1340). Alternatively, the monitoring server 140 may provide the state monitoring result information to a medical institution server. The medical team terminal may include a terminal owned by a medical team or a terminal provided in a medical institution and may include the PC, the mobile terminal, the tablet PC, or the laptop PC.
The user terminal or the medical team terminal displays the received state monitoring result information on the screen. Logical blocks, modules or units described in connection with embodiments disclosed herein can be implemented or performed by a computing device having at least one processor, at least one memory and at least one communication interface. The elements of a method, process, or algorithm described in connection with embodiments disclosed herein can be embodied directly in hardware, in a software module executed by at least one processor, or in a combination of the two. Computer-executable instructions for implementing a method, process, or algorithm described in connection with embodiments disclosed herein can be stored in a non-transitory computer readable storage medium.
The present invention has been described with reference to the preferred embodiments, but those skilled in the art will understand that the present invention can be variously modified and changed without departing from the spirit and the scope of the present invention which are defined in the appended claims.
The present disclosure relates to a technique capable of monitoring a movement of a user, and more particularly, to a method and a system for monitoring a movement of a user, which can accurately sense a movement of a muscle of the user or bending of a joint by using a flexible tactile sensor and monitor a remedial exercise of the user or correcting an exercise posture of the user by using the sensed movement and bending.
