Flexible sensor for detecting human body motion and production method of flexible sensor

Abstract

The invention relates to a flexible sensor for detecting human body motion and a production method of the flexible sensor. The flexible sensor comprises an electrode layer and a flexible polymer layer disposed on the electrode layer. The flexible polymer layer and the electrode layer have triboelectric charges same in electric charge quantity but opposite in polarity, and electric potential of the electrode layer is changed by means of stretching and retracting of the flexible polymer layer so as to drive electrons to flow between the electrode layer and a ground electrode in a reciprocating manner to generate electric signals. The flexible sensor can be used for detecting the human body motion, is simple in production method, low in cost, optionally adjustable in size, portable, high in detecting precision and the like, can be used for monitoring the human body motion in real time and has promising application prospect in the fields of medical treatment, sports, safety protection and the like.

Description

technical field [0001] The invention relates to a flexible sensor for detecting human motion and a preparation method, and has wide application prospects in the fields of medical diagnosis and treatment, sports, safety protection and the like. Background technique [0002] Human body motion sensors can be used to detect various movements of the human body, such as breathing movements, joint movements, etc., and thus have important applications in the fields of medical diagnosis and treatment, physical fitness, and safety protection. Current human motion sensors include human motion sensors based on optical sensing, human motion sensors based on infrared sensing, and human motion sensors based on pressure sensing. These human body motion sensors can be divided into direct and indirect according to the way of implementation. Direct human motion sensors include human motion sensors based on optical sensing and human motion sensors based on infrared sensing. Due to the limitat...

Problems solved by technology

[0003] However, the motion sensors described above have more or less disadvantages

First of all, most of the above-mentioned devices themselves consume energy and need continuous external energy supply, and in many cases, batteries are used for energy supply, which brings the trouble of replacing batteries

Secondly, the monitoring equipment is complex, and some human motion sensors require many additional accessories, which are bulky and heavy

These disadvantages greatly limit their practical application
