Rotary friction nanometer generator

Abstract

The invention provides a rotary friction nanometer generator, which comprises a charge supplementing strip, a dielectric layer and an induction electrode layer, and is characterized in that the induction electrode layer comprises 2N (N is an integer) electrode units arranged around a rotating shaft, every two adjacent electrode units are not communicated with each other, and every two adjacent electrode units are communicated with each other to form two output ends of the generator; the charge supplementing strip and the induction electrode layer are arranged to be mutually fixed; and the dielectric layer and the induction electrode layer are spaced by a set distance, the dielectric layer can rotate around the rotating shaft, the dielectric layer sequentially passes through the upper portions of the two adjacent electrode units in the rotating process, and the surface, facing the induction electrode layer, of the dielectric layer rubs against the charge supplementing strip. The generator disclosed by the invention adopts a simple structure, and the output performance of the rotary friction nano generator can be efficiently enhanced for a long time. The defects that in the prior art and method, the effect is short, and special requirements for equipment or circuits exist are overcome.

Description

technical field [0001] The invention relates to the field of energy transfer conversion, in particular to a performance-improved friction nanometer generator mechanism. Background technique [0002] Triboelectric nanogenerator is a kind of energy device that can effectively convert mechanical energy into electrical energy. The principle of its power generation is friction electrification and electrostatic induction. Rotary triboelectric nanogenerators can convert mechanical energy into electrical energy and achieve high-frequency output, which has unique advantages. However, the high-frequency rotation of the rotary generator will cause severe wear between the electrification layer (usually a dielectric material) and the metal electrode, and if a non-contact type with a certain distance between the electrification layer and the metal electrode is used, it will Reduced output due to insufficient electrification. [0003] The existing method is to conduct high-voltage polari...

Problems solved by technology

However, the output improvement achieved by these methods will fail in a short time because the one-time supplementary charge is easily dissipated.

Moreover, these methods usually require special equipment such as high-voltage sources, plasma generators, etc.

In addition, there are some charge pumping methods that require complex electrical components and circuit design
