Rotary-type compound nanometer power generator

Abstract

The invention provides a rotary-type compound nanometer power generator. The rotary-type compound nanometer power generator comprises a friction nanometer power generation assembly and a magnetic-electric sensing power generation assembly, wherein the friction nanometer power generation assembly comprises a rotor and a stator which are provided with a command rotation shaft, a friction layer is arranged on the lower surface of the rotor and is formed by outwards and radially arranging a plurality of friction units taking the rotation shaft as a circle center, an electrode layer of the stator comprises a first electrode and a second electrode which are formed by outwards and radially arranging a plurality of first electrode units and a plurality of second electrode units at intervals in the same plane from the rotation shaft, electron gain-loss capability difference exists between the friction units and the upper surface material of the stator, a magnet part and a coil part of the magnetic-electric sensing power generation assembly are separately arranged on the rotor and the stator, and under the effect of an external force, induction potential difference is generated between the two electrodes, and meanwhile, induction current is generated in the coil part. The power generator provided by the invention can acquire current output with milliamperes and can be used for directly supplying power to a small-sized power utilization device.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a rotary composite nanometer generator formed by coupling friction effect and magnetoelectric effect. Background technique [0002] With the depletion of traditional fossil fuels (coal, oil and natural gas, etc.) with limited reserves, the energy problem has become a shackle restricting the development of human society. Researchers at home and abroad have turned their attention to renewable new energy sources. Among them, the nanogenerator proposed to solve the energy supply of micro-nano devices and systems has increasingly become the leader leading the development of micro-nano energy. [0003] There have been many reports on nanogenerators based on piezoelectric effect, pyroelectric effect, friction effect, and magnetoelectric effect.
