The invention provides a wind energy friction nano-generator, which comprises at least one power generation device. In each power generation device, a top friction power generation assembly and a bottom friction power generation assembly are oppositely arranged and a ventilation channel is formed between the top friction power generation assembly and the bottom friction power generation assembly; a dithering module is arranged in the ventilation channel; the dithering module is driven to dither when wind passes through the ventilation channel, so that frictional electrification and electrostatic induction coupling effects are generated between the dithering module and the top friction power generation assembly and between the dithering module and the bottom friction power generation assembly; each periodic contact-separate wind energy friction nano-generator unit can collect mechanical energy in a wind environment and convert the mechanical energy into useful electrical energy; and wind energy friction nano-generator arrays are connected in parallel by a peripheral circuit and a rectifier bridge, so that output current of each power generation device can be increased. Output power of a power generation device array is optimized under the condition of impedance matching of an external load; and the working durability and stability of the wind energy friction nano-generator are improved.
Description
technical field [0001] The invention relates to a wind energy friction nano generator, which belongs to the technical field of nano power generation. Background technique [0002] Triboelectric nanogenerator (TENG) is a new type of nanogenerator developed by the Z.L.Wang research group of Georgia Institute of Technology in 2012. TENG is a device that converts mechanical energy into electrical energy using triboelectrification and electrostatic inductive coupling effects, which works differently from various power generation technologies known in the prior art. [0003] Wind energy is not only the most common, abundant source, reliable, low-cost, fuel-free and environmentally friendly renewable energy in nature and daily life, but also an important energy source for driving triboelectric nanogenerators. . However, in the process of realizing the present invention, the applicant found that there is no wind energy triboelectric nanogenerator that utilizes periodic contact-sep...
