Triboelectric nanogenerators (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.

用于生物运动能量收集的直流织物摩擦电纳米发电机。

摩擦电纳米发电机(TENGs)已证明了其在生物运动能量收集方面的潜力。TENG和纺织材料的结合为智能织物提供了一种有效的方法。但是,大多数具有交流电(AC)的传统织物TENG必须使用坚固,不舒服且不友好的整流桥来获得直流电(DC),以存储和供电给电子设备。在这里,最平整的DC结构TENG(DC F-TENG)被设计为通过巧妙地利用衣服的有害和烦人的静电击穿现象来收集生物运动能量。一个小的DC F-TENG(1.5厘米×3.5厘米)可以轻松点亮416个串联的发光二极管。此外,一些纱线超级电容器被制造并编织到DC F-TENG中,以收集和存储能量并为电子设备(例如温湿度计或计算器)供电,在实践中显示出极大的便利性和高效率。这种低成本,高效率的直流F-TENG,可以通过不健康的静电击穿来收集能量而无需使用整流桥直接产生直流能量,它作为轻巧,灵活,可穿戴和舒适的能量收集设备,在未来具有巨大的潜力。
