Electrostatic generator based on ultra-smooth material

Abstract

The invention provides an electrostatic generator based on an ultra-smooth material; the electrostatic generator comprises a stator and a rotor, wherein the rotor comprises a first conductive layer (1); the stator comprises a first insulating layer (2), a second conductive layer (3), a second insulating layer (4) and a third conductive layer (5); and the optimal structural parameters are provided,and the output efficiency of the electrostatic generator is improved. By utilizing a micro-machining process, the thickness of the first insulating layer and the thickness of the second insulating layer are reduced, so that the electrostatic resistance can be reduced to the mu N level, and the application range and the application capacity are improved. The extremely low friction force greatly reduces the energy of the friction loss, so that the conversion efficiency of the generator is improved to an extremely high level.

AI Technical Summary

Problems solved by technology

[0010] Although the research work of these generators has made pioneering progress, due to the existence of friction and wear problems, the relevant structural parameters cannot reach the optimal state, making it difficult for micro electrostatic generators to be applied; the main reasons include: 1. Friction The resulting energy loss greatly reduces the energy conversion efficiency, and also increases the external force required to drive the generator, which limits its application range

2. The wear problem greatly reduces the service life of the generator

3. In order to avoid wear and tear, some complex structures are adopted to greatly reduce the output performance

[0012] However, although the above solution reduces or avoids the wear caused by direct sliding to a certain extent, there are still problems, for example: 1. In order to avoid the air layer caused by the suspended structure is very easy to break down, it is not conducive to improving the charge storage of the generator 2. The suspension structure adopted is very complicated, and it is difficult to miniaturize the generator; 3. Even if wear-resistant materials and liquid lubrication are used, the problems of generator life and conversion efficiency cannot be solved

[0013] It can be seen that due to the existence of problems such as friction and wear in the current electrostatic micro-generator, the relevant structural parameters cannot reach the optimal situation (in order to avoid friction and wear), and in order to achieve the optimal parameters, it is often unavoidable to need contact type of sliding (will cause wear)
