Problems solved by technology

The surface electrostatic charge in the triboelectric nanogenerator is generated by friction or contact between two surfaces. Generally, severe friction or contact is easy to generate high charge density, but in this case, the surface is prone to greater heat and wear, which will greatly affect Device life; at the same time, the charge density is also constrained by air breakdown, which restricts the further improvement of the surface charge density and output power density

Abstract

A nanogenerator system and a power supply device. The nanogenerator system comprises: an electrode layer; a floating layer; a dielectric layer provided on an upper surface and / or lower surface of the floating layer; and a charge pump connected to the floating layer and injecting an electric charge into same. When the floating layer makes a relative movement relative to the electrode layer, the generator system outputs an electrical signal to an external circuit. A combination of the floating layer and / or the floating layer and the dielectric layer is used as the equivalence of at least one friction layer having triboelectrification and electrostatic charge storage functions. An electric charge can be controllably injected into the floating layer in real time.

Description

technical field [0001] The disclosure belongs to the technical field of nano new energy and mechanical energy collection, and relates to a nano generator system and a power supply device. Background technique [0002] The basic principle of triboelectric nanopower generation technology is that when at least one of the two surfaces in contact or friction is an insulating material, friction or contact is used to induce static charges on the two surfaces. When the two surfaces in contact are separated, the separation of static charges A potential difference is generated, resulting in a directional movement of free charges in the sensing electrodes, so that the mechanical energy in the environment can be collected and converted into electrical energy. Frictional nano-power generation technology is especially suitable for collecting low-frequency mechanical energy. It has the advantages of simple structure, low cost, and rich material selection. It has potential application value...
