Abstract

The invention provides a friction generator which includes a first base plate, a second base plate and multiple elastic components. The first base plate is arranged opposite to the second base plate; and the first base plate and the second base plate are connected to each other through the multiple elastic components in a supported manner. A first support material layer, a first electrode layer and a first macromolecular polymer insulation layer are orderly disposed, in the direction opposite to the second base plate, on the first base plate; and a second support material layer, a second electrode layer and a second macromolecular polymer insulation layer are orderly disposed, in the direction opposite to the first base plate, on the second base plate. The cross sections, in the direction perpendicular to the base plates, of the first support material layer and the second support material layer are zigzag in shape. The invention also provides a friction generator set which is composed of at least two friction generators connected in series or in parallel.

Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to the field of a nanogenerator for triboelectric power generation. Background technique [0002] Energy harvesting and conversion devices constructed using nanotechnology, which play a key role in self-powered nanosystems, have attracted increasing attention due to their environmental protection, energy-saving, and self-driving properties. Since the piezoelectric nanogenerator developed by Professor Wang Zhonglin's research group converted mechanical energy into electrical energy for the first time, nanogenerators with different structures and materials based on piezoelectricity and triboelectricity have come out one after another. At present, nanogenerators have been able to drive small liquid crystal displays, low-power light-emitting diodes, and microelectronic devices and modules, etc., but the output power of the generator is still a key factor restricting its development and app...
