Problems solved by technology
However, the structure is too complicated, and it is necessary to lay a straight aisle for the array pressure sensor and a camera aligned with the array aisle, which increases the assembly cost
The tester's feet also need to wear cuffs with built-in acceleration sensors and central processing units, which are uncomfortable to wear and limit the tester's activities, so that it is impossible to grasp the real gait data
In addition, due to the requirements of experimental equipment, this set of gait analysis system can only be applied in the laboratory environment, and cannot be widely used on a large scale

The present invention relates to a gait analysis system based on a high-deformation strain sensor. The gait analysis system based on the high-deformation strain sensor comprises a strain gauge, an induction circuit, a data processing unit, a microcontroller, a wireless communication module, a power supply module, and an intelligent terminal placed in an insole; one end of the induction circuit iselectrically connected to the strain gauge, the other end of the induction circuit is electrically connected with the data processing unit, the microcontroller is electrically connected to the data processing unit, the wireless communication module, and the power supply module, respectively, and the wireless communication module is also communicatively connected to the intelligent terminal. The provided gait analysis system based on the high-deformation strain sensor has characteristics of simple structure and easy wear. Since the strain gauge is placed in the insole of the foot, discomfort isnot caused to a user and at the same time, authenticity of measurement data is also not affected; and in addition, the provided gait analysis system has relatively strong practicability and stabilityand a monitoring device is not liable to fall off and high in stability; and the gait analysis system is low in monitoring cost and suitable for most people.
Description
technical field [0001] The present invention relates to a gait analysis system, more specifically, to a gait analysis system based on a high deformation strain sensor. Background technique [0002] Different gaits can be reflected from the distribution and size of the sole pressure, which in turn reflects the information of the lower limb motor function of the human body. When lesions occur in the lower extremities, the distribution of plantar pressure will also change accordingly. By detecting and analyzing the relevant parameters of plantar pressure to obtain certain physiological or pathological information of the human body, it is useful for clinical medical diagnosis, surgical effect evaluation, rehabilitation training, etc. All have important scientific significance and application value. [0003] The invention patent with application number 201220605605.X discloses a human gait analysis system based on motion recognition technology, which includes a host computer and...
