A triboelectric nanogenerator

Abstract

The invention relates to the technical field of nano-generators, and discloses a friction nano-generator which is applicable to collecting ocean energy. The friction nano-generator comprises a housingwith a closed structure to form a friction space inside and a rolling body located in the friction space, wherein the housing includes a packaging shell, an induction electrode group located at the inner side of the packaging shell and a friction layer located at the side, which is away from the packaging shell, of the induction electrode group, the induction electrode group includes a first induction electrode and a second induction electrode which are distributed along the inner side surface of the packaging shell and insulated from each other; and both the rolling body and the friction layer are made of a silica gel material, and the rolling body can have moderate flexibility, so that the surface contact between the rolling body and the friction layer is enabled to be good, and the rolling of the rolling body is also easy to realize at the same time. The friction nano-generator is particularly applicable to collecting the mechanical energy of low-frequency motion. In addition, theadopted silica gel material enables the impact resistance of the friction nano-generator to be significantly enhanced.
