Embodiment Construction

[0016] Below, the specific implementation manners of the present invention will be further described in conjunction with the accompanying drawings.

[0017] attached figure 1 Represents a typical structure of a polymer-based triboelectric generator. The triboelectric generator is like a sandwich structure consisting of two different polymer sheets stacked on top of each other without any adhesive between the layers. Such as figure 1 As shown, a rectangular (4.5cm×1.2cm) polyimide film (thickness 125μm, DuPont 500HN, attached image 3 Kapton) as the first electrode polymer insulating layer 4, placed on the second polymer insulating layer 2 flexible polyester film substrate (thickness 220 μm, attached image 3 in PET). The two short edges of the device were sealed with common tape to ensure proper contact between the two polymer insulating layers. The two surfaces of the top and bottom of the structure are coated with an alloy metal film 1 (thickness 100nm, attached image...

Abstract

The invention provides a friction generator. The friction generator comprises two electrodes; the electrode comprises a macromolecular polymer insulating layer; a micro-nano concave-convex structure is arranged on one side surface of the macromolecular polymer insulating layer, and a metal film is arranged on the other side surface; the surface of the electrode micro-nano concave-convex structure of one insulating layer is directly attached to the surface of the electrode micro-nano concave-convex structure of the other insulating layer, and the two are fixedly connected through the outer edge; and the metal film is an electrode for outputting voltage and current of the friction generator. The invention provides a novel and effective method for obtaining energy by use of the friction effect. The friction generator generates electric energy by use of the potential change of the internal electrification by friction and the inductive effect of the metal pole plates on the two sides; and the method is simple and efficient and the cost is low.

Description

Background technique [0001] Energy harvesting and conversion devices using nanotechnology are likely to play a key role in the manufacture and driving of self-powered nanodevices and nanosystem devices due to their unique self-generating and self-driving properties. Recently, researchers from various countries have received more and more attention. 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 drive commercial light-emitting diodes (LEDs), small liquid crystal displays, and even self-powered wireless data transmission devices. The power density ha...
