Flexible wearable sensor for detecting foot movements and manufacturing method thereof

Abstract

The invention relates to the field of movement monitoring sensors and discloses a flexible wearable sensor for detecting foot movements. The flexible wearable sensor comprises a fabric article, a supporting layer, a sensitive material layer, an electrode layer and a protective layer, wherein the electrode layer comprises at least two electrodes led out of the sensitive material layer or the surface of the sensitive material layer, the sensitive material layer is made from a three-dimensional porous nano sensitive material, and the protective layer and the supporting layer are composed of flexible high-molecular polymers, have biocompatibility and jointly wrap the sensitive material layer. The invention further discloses a manufacturing method of the flexible wearable sensor for detecting the foot movements and a monitoring system based on the sensor. The sensor is light, thin and soft, can be processed to be in various shapes and can be worn and attached to the sole, acquire pressure data produced by the foot during movements and effectively monitor the foot movements.

Description

technical field [0001] The invention relates to the field of movement monitoring, in particular to a flexible wearable sensor for detecting foot movement and a preparation method thereof, and to a monitoring system based on the flexible wearable sensor for detecting foot movement. Background technique [0002] With the development of social economy and the improvement of people's living standards, people pay more and more attention to health problems. Exercise has become a main way for people to maintain their health, and regular and reasonable exercise is very important for maintaining their health. However, how to adjust the exercise intensity and exercise time in time according to the individual's physical condition during exercise, and how to reasonably control the amount of exercise within the optimal range is a problem in exercise. If conditions permit, you can go to the gym to exercise under the guidance and supervision of a sports coach. The coach's responsibility i...

If conditions permit, you can go to the gym to exercise under the guidance and supervision of a sports coach. The coach's responsibility is equivalent to monitoring the human body movement process involved in fitness and giving feedback, but regardless of economic or geographical conditions, it is not Everyone can go to the gym to exercise, and there are some people who are only keen on outdoor sports

Then, without the monitoring of a fitness coach, excessive exercise may cause muscle strain and other adverse effects on the health of the athlete, while too little exercise will not achieve the effect of exercise, so the exercise process needs to be monitored and based on the monitoring results Adjust exercise time, intensity and frequency to achieve the purpose of healthy exercise

[0003] However, there are not many existing human motion monitoring methods, such as video analysis, through proper processing of video camera signals, the number of motions can be counted, but this process requires very complex background separation algorithms and high-speed data acquisition, so the cost Higher; there are other contact pedometers that detect the movement of the waist and hips of the human body. This device needs to be hung on the waist at all times, which is not convenient during exercise; in addition, other devices such as infrared devices and equipment dedicated to motion monitoring The price is relatively expensive, and the equipment is bulky and inconvenient to carry
