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

The invention discloses a nanometer generator system and a power supply device. The nanometer generator system comprises an electrode layer, a floating layer, a dielectric layer arranged on the uppersurface and/or the lower surface of the floating layer, and a charge pump connected with the floating layer and used for injecting charge into the floating layer; and the generator system outputs an electric signal to an external circuit when the floating layer moves relative to the electrode layer. The floating layer and a combination of the floating layer and the dielectric layer are used as equivalence of at least one friction layer with friction electrification and electrostatic charge storage functions; and the charge can be controllably injected into the floating layer in real time through the charge pump. The charge density of the nanometer generator system is no longer generated by mainly depending on friction or contact and is not restricted by air breakdown and the like; and thenanometer generator system has high power output density.

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...
