Electrostatic energy harvesting device based on paper folding springback mechanism

The invention discloses an electrostatic energy harvesting device based on a paper folding springback mechanism. The device comprises a paper folding structure, a dielectric pair and an electric energy transmission circuit, wherein the dielectric pair is fixed on the surface of the paper folding structure; the dielectric pair comprises two dielectric material layers with opposite polarities and two metal electrode layers, and the paper folding structure can be compressed and rebounded along a certain direction, so that the dielectric pair is contacted and separated to generate charge transfer,mechanical energy is converted into electric energy, and the electric energy is transmitted through the electric energy transmission circuit. The electrostatic energy harvesting device is ingenious in structure, novel in form, capable of saving energy and environmentally friendly, the periodical paper folding structure provides a larger effective surface area under a certain size, the space utilization rate is high, and
