Double-layer staggered sprocket type friction nanometer generator

Abstract

The invention discloses a double-layer staggered sprocket type friction nano-generator which is composed of a plurality of units and a frame, each unit of the units is composed of a plurality of sprockets made of acrylic plates, copper films are plated on the sprockets to serve as electrodes of the friction nano-generator, and the frame is made of acrylic materials. Sponge is attached to the surface of the frame, and a polyimide film is attached to the sponge to serve as an independent layer. The double-layer staggered zipper tooth type friction nanometer generator can convert mechanical energy from linear or rotary mechanical motion into electric energy, is a sustainable energy source, can be combined with a zipper structure, and has the advantages that compared with a traditional zipper, the double-layer staggered zipper tooth type friction nanometer generator is more energy-saving and environment-friendly; the double-layer staggered zipper tooth type friction nanometer generator can generate electric energy in the continuous pulling process of the zipper, and the generated electric energy after rectification can lighten more than 15 LED lamps and can also supply power to electronic equipment.

Description

technical field [0001] The invention relates to the technical field of nanogenerators, in particular to a double-layer interlaced sprocket friction nanogenerator. Background technique [0002] Nanogenerator is a nanogenerator based on regular zinc oxide nanowires, which converts mechanical energy into electrical energy in the nanometer range. It is the smallest generator in the world. At present, nanogenerators can be divided into three categories, one is pressure Electric nanogenerators, piezoelectric nanogenerators are micro-generators that use the piezoelectric properties and semiconductor properties of special nanomaterials to convert mechanical energy of bending and compression into electrical energy. There is also a type of triboelectric nanogenerators, which use Two kinds of materials with different ability to bind electrons, the micro motors that gain and lose electrons when they contact each other and generate current in the external circuit, currently have four mai...

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-layer interlaced chain-tooth type friction nanogenerator to solve the problem that the existing friction nanogenerator proposed in the above background technology is difficult to combine with objects in real life to achieve the effect of friction power generation. Narrow, due to the increasing shortage of electric energy in social development, it is difficult to use triboelectric nanogenerators as a sustainable energy source in daily life
