Application of clothing friction nanopower generators in human motion energy acquisition

Abstract

In order to monitor the movement state of the human body and fully collect the energy generated by human body motion, taking a fully flexible integrated friction nanogenerator as an example, the application of clothing friction nanopower generators in human motion energy acquisition is researched. The fully flexible integrated friction nanogenerator is prepared by vulcanizing silica gel, high-temperature-vulcanized silica gel and silver-plated glass powder, and the friction nanogenerator is used to collect the energy generated by human motion. The experimental results show that when the fully flexible integrated friction nanogenerator is placed on the elbows, underarms, knees and soles of the feet, it can collect the energy generated by the movements of the human body, such as walking, tapping and swinging of arms. The corresponding short-circuit current is output, and the mechanical energy generated by human motion is converted into electrical energy. The current performance of the friction nanogenerator is stable in the optimal frequency range, and human motion energy in the low-frequency band can be efficiently collected, and the human motion posture is monitored by the current output values in different states.
