Abstract

The invention provides a liquid-based friction generator, a power generation method and a sensor. The friction generator comprises a friction layer of which the upper surface is provided with a first conductive element in a contacting manner, and a liquid into which a second conductive element is immersed; the lower surface of the friction layer and the upper surface of the liquid are arranged in a face-to-face manner; at least one part of the lower surface of the friction layer can be separated from the upper surface of the liquid after contacting with the upper surface of the liquid; and electric signals can be outputted to the outside through the first conductive element and the second conductive element. Correspondingly, the invention also provides a sensor and a friction power generation method. According to the friction generator, friction power generation of the liquid and the solid friction layer and electrostatic conduction principles are utilized; and the liquid and solid contact-based friction generator is designed and is simple in structure, and can collect mechanical energy generated by liquid fluctuation, and convert the mechanical energy into electrical energy, and has a broad application prospect.

Description

Technical field [0001] The present invention relates to the technical field of friction power generation, in particular to a friction generator and a power generation method that converts liquid fluctuating mechanical energy into electric energy, and a sensor using the friction generator. Background technique [0002] Various kinetic and potential energies will continue to be produced during the existence of nature and human life. How to transform these tiny energies into the source of driving force we need is the direction that people are constantly exploring. In 2006, the Wang Zhonglin research group of Georgia Institute of Technology in the United States put forward the concept of nano generators, which opened 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 triboelectricity show new application value and potential through reasonable design of the device structure. The entir...
