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.
摩擦纳米发电机（TENGs）已在生物运动能量收集方面展现出其广阔的应用潜力。TENG与纺织材料相结合为智能织物提供了一种有效途径。然而，大多数传统的交流（AC）织物TENG必须使用僵硬、不舒适且不友好的整流桥来获取直流电（DC），以便为电子设备存储和供电。在此，设计了一种具有最常见平纹结构的直流织物TENG（DC F-TENG），通过巧妙利用衣物有害且恼人的静电击穿现象来收集生物运动能量。一个小型的DC F-TENG（1.5厘米×3.5厘米）能够轻松点亮416个串联的发光二极管。此外，制造了一些纱线超级电容器并将其编织到DC F-TENG中，以收集和存储能量，并为诸如温湿度记录仪或计算器等电子设备供电，这在实际应用中显示出极大的便利性和高效性。这种低成本且高效的DC F-TENG能够通过从不健康的静电击穿中收集能量直接产生直流电，而无需使用整流桥，未来作为一种轻质、灵活、可穿戴且舒适的能量收集设备具有巨大潜力。
