Friction nanogenerator

Abstract

The invention relates to the field of nano new energy and wave energy collection, and discloses a friction nanogenerator. The friction nanogenerator comprises a shell body and a generator assembly, wherein the generator assembly is arranged inside the shell body; the generator assembly comprises a plurality of generator units; each generator unit comprises two oppositely arranged blocking pieces,a rolling disk positioned between the two blocking pieces, and a rollway arranged on the circumferential side of the rolling disk and matched with the two blocking pieces to form a rolling disk motioncavity; the rolling disk can be arranged in the rolling disk motion cavity in a rolling manner relative to the blocking pieces along the inner surface of the rollway; and at least one of the blockingpieces comprises a base plate, and a first friction electrode unit and a second friction electrode unit which are arranged on one side, facing the rolling disk, of the base plate and are mutually insulated. The friction nanogenerators is compact in structure, can generate an alternating current and loading the alternating current to a load by means of friction electrode layers under the action ofwave excitation based on motion of the rolling disk, realizes the absorption of the wave energy and converts the wave energy into electric energy.

Description

technical field [0001] The invention relates to the fields of nano new energy and wave energy collection, in particular to a friction nano generator. Background technique [0002] The constraints of resources and environment in modern society put forward higher requirements for clean and renewable energy, and wave energy as a clean energy has great potential for application, but the existing wave energy collection technology generally uses electromagnetic generators, which is technically complicated. , high cost and other limitations, and after years of development, it is still in the stage of small-scale test operation. [0003] The basic principle of triboelectric nanopower generation technology is to use friction (contact) to generate static charges on two surfaces (at least one of which is insulating material). The charge moves in a directed manner, thereby harvesting the mechanical energy in the environment and converting it into electrical energy. Triboelectric nanop...
