Abstract

The invention discloses a cantilever beam-type composite nano generator, which comprises a first cantilever beam, a second cantilever beam and a piezoelectric power generation assembly (50), wherein the first cantilever beam can elastically vibrate and comprises a first friction power generation assembly; the second cantilever beam can elastically vibrate and is used for being horizontally contacted with the first cantilever beam when at rest; the second cantilever beam comprises a second friction power generation assembly and is used for being contacted with or separated from the first friction power generation assembly during a vibration process, and during the contact and separation process, a friction potential difference is generated between the first friction power generation assembly and the second friction power generation assembly; and the piezoelectric power generation assembly (50) is arranged on the first cantilever beam and / or the second cantilever beam for generating stretching and / or compression deformation during the vibration process, and a piezoelectric potential difference is generated in the piezoelectric power generation assembly. According to the cantilever beam-type composite nano generator, through vibration between the first cantilever beam and the second cantilever beam, friction electric signals and piezoelectric electric signals are generated, and the energy conversion efficiency can be improved.

Description

technical field [0001] The invention relates to a nanometer generator, in particular to a cantilever beam composite nanometer generator. Background technique [0002] With the depletion of traditional fossil fuels, energy issues have become a shackle that restricts 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 problem of energy supply for micro-nano devices and systems has increasingly become the leader leading the development of micro-nano energy. There have been many reports on nanogenerators based on piezoelectric effect, pyroelectric effect, friction effect, and magnetoelectric effect. [0003] However, the energy conversion efficiency of a single form of nanometer power generation device is not high, which limits its practical application. How to maximize energy conversion efficiency has become the core of micro-nano energy research, for ...
