Abstract: Triboelectricnanogenerators (TENGs) have demonstrated their promising
potential in biomotion energy harvesting. A combination of the TENG
and textile materials presents an effective approach toward smart
fabric. However, most traditional fabric TENGs with an alternating
current (AC) have to use a stiff, uncomfortable, and unfriendly rectifier
bridge to obtain direct current (DC) to store and supply power for
electronic devices. Here, a DC fabric TENG (DC F-TENG) with the most
common plain structure is designed to harvest biomotion energy by
tactfully taking advantage of the harmful and annoying electrostatic
breakdown phenomenon of clothes. A small DC F-TENG (1.5 cm ×
3.5 cm) can easily light up 416 serially connected light-emitting
diodes. Furthermore, some yarn supercapacitors are fabricated and
woven into the DC F-TENG to harvest and store energy and to power
electronic devices, such as a hygrothermograph or a calculator, which
shows great convenience and high efficiency in practice. This low-cost
and efficient DC F-TENG which can directly generate DC energy without
using the rectifier bridge by harvesting energy from unhealthy electrostatic
breakdown has great potential as a lightweight, flexible, wearable,
and comfortable energy-harvesting device in the future.
