Clingy type friction generator

Abstract

The invention discloses a clingy type friction generator. The friction generator comprises a friction power generation assembly (100), and is characterized in that the friction power generation assembly (100) comprises a first friction power generation unit (110) and a second friction power generation unit (120) which are oppositely arranged, and mutual contact friction exists between the first friction power generation unit (110) and the second friction power generation unit (120) so as to be able to generate electric energy; the first friction power generation unit (110) and the second friction power generation unit (120) of the friction power generation assembly (100) are arranged in a contact mode when the friction generator is at a free state; and the first friction power generation unit (110) and the second friction power generation unit (120) of the friction power generation assembly (100) are mutually separated when the friction generator is at a stress state. Compared with a traditional separated friction generator, the clingy type friction generator disclosed by the invention does not have a problem of activation at an initial stage in use, and is more stable in output signal; and furthermore, at the aspect of micro force detection, signal output is greater and the sensitivity is higher under the condition of the same area.

Description

technical field [0001] The invention relates to a generator, in particular to a close-fitting friction generator. Background technique [0002] When objects rub against each other, one side will be negatively charged and the other side will be positively charged. This kind of electricity generated by friction between objects is called triboelectricity. Triboelectricity is one of the most common phenomena in nature, and the generation conditions of triboelectricity are very wide. A type of generator developed according to the phenomenon of frictional power generation of objects is called a friction generator. [0003] At present, the two friction materials in the existing friction generators are initially separated. When the friction generator is left unused for a long time, the static charge on the surface of the friction materials will gradually dissipate, and when it is used again An "activation" process will be required - the output signal of the friction generator has ...
