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.
