Abstract

A liquid-based friction generator, a generation method, and a sensor. The friction generator comprises a friction layer (10), an upper surface of which is provided with and in contact with a first conducting element (11), and a liquid (20) in which a second conducting element (21) is immersed. A lower surface of the friction layer and an upper surface of the liquid are arranged face to face, at least a part of the lower surface of the friction layer can depart from the upper surface of the liquid after contacting it, and an electric signal can be output by using the first conducting element and the second conducting element. For the friction generator, by using frictional electricity produced by a liquid and a solid friction layer, and according to a static electricity conduction principle, a friction generator that is based on contact between a liquid and a solid and has a simple structure is designed, and mechanical energy produced by liquid wave can be collected and then converted into electrical energy.

Description

technical field [0001] The invention relates to the technical field of friction power generation, in particular to a friction generator and a power generation method for converting mechanical energy of liquid fluctuations into electric energy, and a sensor using the friction generator. Background technique [0002] Nature and human life will continue to produce various kinetic and potential energies. How to transform these tiny energies into the source of driving force we need is a direction that people are constantly exploring. In 2006, Wang Zhonglin's research group at the Georgia Institute of Technology proposed the concept of nanogenerators, opening up a new category of energy conversion and application. On this basis, the research group led by Professor Wang Zhonglin made the ancient phenomenon of triboelectrification show new application value and potential through reasonable design of device structure. The whole triboelectric generator relies on the charge-pump effec...
