Power-generating cloths, wearable devices, and sensors based on triboelectric nanogenerators

Abstract

The invention discloses a power generation cloth, a wearable device and a sensor based on a frictional nanogenerator. Wherein, the power generation cloth includes: a first friction line, a second friction line, and an elastic axis, and the first friction line and the second friction line are braided along the elastic axis; wherein, the first friction line and the second friction line of the power generation cloth The parts where the two friction lines are in contact have different friction electrode sequences; the elastic axis is elastically stretched, and the first friction line and the second friction line are separated from each other; the elastic axis realizes elastic recovery, driving the first friction line and the second friction line to mutually touch. The power generation fabric has high elasticity and good flexibility, can self-supply power, convert various mechanical energy into electric energy output, improve user experience, reduce energy waste to a certain extent, thereby improving environmental pollution problems, high wearing comfort and breathability Good performance, convenient cleaning, simple preparation process, wide selection of materials, low cost, and industrialized large-scale production.

Description

technical field [0001] The invention belongs to the field of energy conversion, and relates to a power generation cloth, a wearable device and a sensor based on a frictional nanogenerator. Background technique [0002] In recent years, more and more wearable electronic products have entered the market. They are quietly changing people's lifestyles and creating considerable market value. However, as the number and types of wearable electronic products continue to increase, their shortcomings are becoming more and more obvious. One of the key issues restricting the development of wearable technology is its service life and standby time. At present, wearable electronic products are powered by rechargeable batteries, and because these electronic products are usually small in size, they can only use very small battery systems, and their powerful functions make the power consumption very large, which is It means that the current wearable devices have a great lack of battery life....

AI Technical Summary

Problems solved by technology

At present, people have successively invented a variety of wearable friction nanogenerators, but most of these generators use metal materials such as aluminum, copper, gold, silver or conductive materials such as carbon fibers and carbon nanotubes as electrodes. Polymer films act as friction materials, which makes them impermeable, impermeable, and poorly integrated with clothing, making them of little practical value
