Cavity multilayer film electret generator structure and its preparation method, energy supply system

Abstract

The invention discloses a cavity-type multilayer film electret generator structure, a preparation method thereof, and an energy supply system. The cavity-type multilayer film electret generator structure comprises an elastic rectangular cavity, wherein the exterior of the elastic rectangular cavity is of a cuboid structure, and the interior forms a cavity; a pressure bearing plate which is locatedon the upper surface of the elastic rectangular cavity; an electret multilayer film structure which is located in the cavity of the elastic rectangular cavity and is attached to the inner bottom surface, wherein a gap is formed between the electret multilayer film structure and the inner upper wall. The electret multilayer film structure includes an electrode layer; a polymer insulation compositefilm which covers a periphery of the electrode layer, wherein the polymer insulation composite film comprises an electret inner core layer and an electrostatic insulation outer sealing layer from inside to outside, and the electrostatic insulation outer sealing layer is attached to the surface charge surface of the electret inner core layer. The generator structure has both good environmental adaptability and high single-time energy collection efficiency. The electrical output of the generator structure is processed by the rectification module and the voltage reduction module and then is supplied as energy, and the generator structure has high stability and safety.

Description

technical field [0001] The disclosure belongs to the technical field of new energy, and relates to a cavity-type multilayer membrane electret generator structure, a preparation method thereof, and an energy supply system. Background technique [0002] Today, when lithium battery power supply has become the mainstream energy supply method for portable mobile appliances, the dependence of traditional batteries on the charging environment has undoubtedly become a major limitation. In addition, discarded batteries will also bring harm to the environment. Human body movement can generate a large amount of energy. Many human movements, such as walking, dancing, dressing, etc., are all related to the transformation of energy. The continuous power of ordinary people is about 70W under normal circumstances. Well-trained athletes, armed police, The instantaneous burst power of public security, soldiers, bodyguards, etc. can reach up to 3kW. In more strenuous exercise, such as playing...

AI Technical Summary

Problems solved by technology

The current electret generator structure generally has problems such as low power, serious body charge attenuation, and high requirements for the working environment.

[0005] In addition, although some micro-electret generators have good environmental adaptability, there is still the problem of low energy collection efficiency.
