Embodiment Construction

[0040] figure 1 A schematic structural diagram of a stretchable triboelectric nanogenerator in a single-electrode mode according to an embodiment of the present invention is shown. like figure 1 As shown, the stretchable triboelectric nanogenerator includes silicone rubber 11 and helical steel wire 12 . Silicone rubber 11 is used as a friction material. The spiral steel wire 12 as an electrode material is formed in the silicone rubber 11 and extends from one end of the silicone rubber 11 . The helical wire 12 is configured to match the Young's modulus of the silicone rubber 11 . The structure of the stretchable triboelectric nanogenerator is fibrous.

[0041] When the skin comes into contact with the silicone rubber, a negative triboelectric charge remains on the surface of the silicone rubber and creates a positive charge on the skin. When separated from the skin, electrons flow from the conductive helical wire 12 to the ground under short-circuit conditions, and a posit...

Abstract

The invention provides a stretchable friction nanogenerator in a single electrode mode and a preparation method thereof. The stretchable friction nanogenerator comprises: organic silicon rubber serving as as a friction material; a spiral steel wire formed in the organic silicon rubber and extending out from one end of the organic silicon rubber, wherein the spiral steel wire is used as an electrode material; and the spiral steel wire is configured to match with the Young modulus of the organic silicon rubber. According to the scheme provided by the invention, the spiral steel wire is used as the electrode material, due to the firmness, the continuous conductivity and the geometric structure of a steel wire electrode, the friction nanogenerator based on the spiral steel wire has high stability, stretchability and customizability. Furthermore, the silicon rubber substrate has good tensile properties, and its properties remain unchanged after being twisted, bent or stretched, thereby being able to meet the requirements of different applications, and being suitable for use on wearable electronic devices.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a single-electrode mode stretchable frictional nanometer generator and a preparation method, a wearable device, an active sensor and a smart glove. Background technique [0002] In recent years, multifunctional wearable electronic products have achieved rapid development, such as smart watches, smart glasses, and electronic skins. These electronic products can simulate the characteristics of human skin, as well as wireless sensor networks applied to monitor human health and movement trajectory. This also poses some challenges for wearable devices, as these devices need to be flexible, lightweight, inexpensive and stable. [0003] However, commercial portable energy storage devices including batteries and supercapacitors are relatively heavy, require frequent recharging, and face severe lifetime limitations. To overcome these challenges, a series of advanced energy harvesting te...
