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 high molecular polymer insulating layer 4 of the first electrode, placed on the second high molecular 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 the bottom of the structure are coated with an alloy metal ...

Abstract

A friction generator and friction generator unit. The friction generator comprises two electrodes, the electrode includes high molecular polymer insulating layer (2, 3), a micro-nano concave-convex structure is disposed on one surface of the high molecular polymer insulating layer, a metal film (1) is disposed on another surface of the high molecular polymer insulating layer. The surface with the micro-nano concave-convex structure (4) of the high molecular polymer insulation layer is fit fixedly against the surface with the micro-nano concave-convex structure of another insulation layer. The metal film is the electrode of the output voltage and current of the friction generator. The friction generator unit is consists of friction generators connected in parallel or in series. The friction generator and friction generator unit produce electricity depending on the change of the internal friction on the electric potential and the induced effect on both sides of the metal plates.

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...
