Abstract

The invention provides a frictional electricity nano-generator, a generator set and a shoe pad utilizing the frictional electricity nano-generator. The frictional electricity nano-generator comprises an upper electrode layer, a first friction layer, an elastic layer, a second friction layer and a lower electrode layer from top to bottom in sequence, wherein the elastic layer is used for isolating the first and second friction layers, and is compressed under the external stress to enable the first and second friction layers to contact with each other; when being not stressed, the elastic layer can be elastically recovered to separate the first friction layer from the second friction layer; and the first and second friction layers are made of materials with different frictional electricity properties. Potential difference can be formed between the upper and lower electrode layers by the continuous contacting and separating of the two polymer layer frictional electricity materials during external stress applying and removing, thus outputting electricity outwards.

Description

technical field [0001] The invention relates to a generator, in particular to a triboelectric nanogenerator which converts naturally existing mechanical energy such as gravity, movement, vibration, etc. into electric energy and an insole using the triboelectric nanogenerator. Background technique [0002] Due to the effect of the earth's gravity, all living things on the earth must overcome their own gravity in the process of moving. How to recover this massively wasted gravitational energy has always been a major research topic. [0003] Utilizing the insole with the power generation device can convert a large amount of gravitational energy lost during walking into electrical energy. At present, the insoles with power generation devices that have been reported are composed of pedaling and rotating mechanisms, transmission mechanisms and micro-generators. This kind of insoles has complex structure, large volume, high cost, and low stability and conversion efficiency. diffi...
