Power generation fabric and power generation garment based on electrostatic friction effect

Abstract

The invention provides a power generation fabric based on an electrostatic friction effect. A first composite yarn (100) comprises a first conductive fiber inner core (101) and a first outer layer material (102); a second composite yarn (200) comprises a second conductive fiber inner core (201) and a second outer layer material (202); the first outer layer material (102) in the first composite yarn (100) and the second outer layer material (202) in the second composite yarn (200) are in different positions on a friction electrode sequence, and can be in contact with each other and can be rubbed. The composite yarns containing the conductive inner cores of different friction electrode sequences is prepared into the power generation fabric and the power generation garment by using an existing textile technology, and the power generation fabric and the power generation garment have the advantages of good safety, convenient cleaning, large-scale production and high comfort.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a power generation cloth and power generation clothes based on electrostatic friction effect. Background technique [0002] Wearable electronic devices such as electronic skins, smart watches, sports bracelets, etc. have gradually shown broad application prospects and huge market potential.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, most friction generators use metal wires or metal films as electrodes. During the friction process, the metal wires are easily broken, and the metal films are easy to fall off, and the electrodes are less safe and difficult to clean, and are wrapped outside the metal electrodes. The material is usually made of flexible polymers, although it can achieve continuous power supply, it is usually not comfortable and aesthetically pleasing

In addition, the preparation process of the friction layer of the existing friction generator is complex and precise, and the preparation process has a great impact on the power generation performance. Although it has weavability, it does not match the existing commercial production technology, which is not conducive to large-scale production

Therefore, in order to realize the wide application and commissioning of friction generators, it is urgent to solve the problems of poor safety, difficult cleaning, difficulty in large-scale production and low comfort of existing friction generators.
