contact friction nanogenerator

Abstract

The invention discloses a contact friction nanogenerator, comprising: a first friction unit, a second friction unit and a moving part; the moving part is located between the first friction unit and the second friction unit; The first friction unit has a plurality of first removal regions arranged at preset intervals, the second friction unit has a plurality of second removal regions arranged at preset intervals, and the plurality of first The removal area and the plurality of second removal areas are distributed alternately; when the moving part moves relative to the first friction unit and the second friction unit, the moving part and the first friction unit respectively The friction unit and the second friction unit generate friction. The contact friction nanometer generator can effectively collect the mechanical energy of relative sliding in the surrounding environment, and its power generation efficiency is better than that of the nanometer generator with a contact separation structure in the prior art.

Description

technical field [0001] The invention relates to the field of nanotechnology, more specifically, to a contact friction nanometer generator. Background technique [0002] Energy shortage is a major problem facing human society today, and the development of new energy technologies and energy-saving technologies has become an important subject in the field of science. Energy harvesting and conversion devices using nanotechnology have unique self-generating and self-driving properties, and are likely to be used in manufacturing It plays a key role in driving self-powered nanodevices and nanosystem devices. Since the research group of Professor Wang Zhonglin from the Georgia Institute of Technology in the United States first successfully realized the piezoelectric nanogenerator that uses zinc oxide nanowires to convert mechanical energy into electrical energy in 2006, based on the piezoelectric effect, people have successively developed different materials and generators. Various...
