Abstract

The invention relates to the field of generators, and discloses an improved friction nano-generator, comprising a first power generation part and a second power generation part, wherein the first power generation part comprises a first friction layer; and a first ferroelectric layer; wherein the first friction layer is disposed on a surface of the first ferroelectric layer; the second power generation part includes a second electrode; the second electrode outputs electrical energy when mutual friction of the second power generating part and the first friction layer occurs. By polarization of the built-in medium introduced to the ferroelectric layer material, the friction charge density of the friction layer is improved and the generator output with higher power density can be obtained.

Description

technical field [0001] The invention relates to a generator, in particular to an improved friction nanometer generator which converts mechanical energy into electrical energy. Background technique [0002] Due to the energy crisis and environmental pressure, people have been devoting themselves to the study of maintaining the huge energy consumption of modern society while minimizing the consumption of the environment. Harvesting energy from renewable natural environments is an effective solution to alleviate the energy crisis. In 2012, academician Wang Zhonglin invented the triboelectric nanogenerator (TENG), which is used to harvest the mechanical energy that is ubiquitous in the environment but is often wasted. It has been proved to be a far-reaching solution. Previous work on triboelectric nanogenerators has demonstrated its potential for a wide range of applications, from self-propelled systems that drive small electronics to harvesting low-frequency ocean wave energy ...
