Abstract

The invention discloses a friction energy collector and a preparation method thereof. The friction energy collector comprises a power generation device and a cantilever beam structure; the power generation device comprises a first supporting layer, a first friction layer, a second friction layer and a second supporting layer; and the cantilever beam structure comprises a fixed support and a free end. The friction energy collector is characterized in that the power generation device and the cantilever beam structure are arranged, wherein the power generation device is composed of the supportinglayers, the friction layers and other components, so that the friction energy collector is simple in structure, light in weight, easy to manufacture, capable of being produced in batches, and relatively high in energy conversion efficiency. The device is miniaturized and integrated, so that the output performance of the miniature energy collector is improved. Mechanical movement is converted intoelectric energy through various modes such as beating, vibration, friction and the like.

Description

technical field [0001] The invention relates to the field of energy harvesting, in particular to a frictional energy harvester and a preparation method thereof. Background technique [0002] Due to the increasing consumption of non-renewable energy and the increasingly prominent environmental problems, the development and research of green new energy will become a new trend. The triboelectric effect is one of the few effects that has been known for thousands of years, a phenomenon we experience every day and that can be used to convert mechanical energy into electrical energy, i.e. triboelectricity. As a new research field, new technologies and micro-nano materials can be used to efficiently collect and store energy in the environment to achieve sustainable operation of micro-nano systems. [0003] Frictional energy collection, collecting relative friction in the environment, and frictional energy exists widely, and unlike light energy, thermal energy, etc. are limited by n...
