Friction generator

Abstract

The invention provides a friction generator, which comprises a first electrode, a second electrode and an intermediate film, wherein the first electrode comprises a first macromoleclar polymer insulation layer of which one side surface is provided with a conductive film; the second electrode comprises a second macromoleclar polymer insulation layer of which one side surface is provided with a conductive film; the intermediate film is fixed on the other side surface of the second macromoleclar polymer insulation layer; the non-fixed surface of the intermediate film is provided with a micro-nano concave-convex structure; the surface of the micro-nano concave-convex structure of the intermediate film on the second electrode and the surface without the conductive film of the first electrode are oppositely fit and are mutually fixedly connected; and the conductive film of the first macromoleclar polymer insulation layer and the conductive film of the second macromoleclar polymer insulation layer are both the voltage and current output electrodes of the friction generator. The invention provides an innovated and effective method by the friction action, and electricity energy is generated by the variation of internal friction electrification electric potential and the induction effect of metal pole plates on two sides. The method is simple and efficient and has low cost.

Description

technical field [0001] The invention relates to a power generation device, in particular to a miniature friction power generation device. Background technique [0002] Energy harvesting and conversion devices using nanotechnology, due to their unique self-generating and self-driving properties, are likely to play a key role in the manufacture and driving of self-powered nanodevices and nanosystem devices. Recently, researchers from various countries have received more and more attention. more and more attention. In 2006, the research group of Professor Wang Zhonglin from the Georgia Institute of Technology successfully realized the piezoelectric nanogenerator that uses zinc oxide nanowires to convert mechanical energy into electrical energy for the first time. Subsequently, based on the piezoelectric effect, various nanogenerators based on different materials and structures have been successively developed. Currently, the output power of nanogenerators is sufficient to dri...
