The device was constructed by silicone rubber, woven conducting textiles, nylon mesh spacer, and ethylene vinyl acetate textile. The physical mechanism of TENG is related to Maxwell’s displacement current, in short, it’s based on a coupling effect of contact electrification and electrostatic induction. This result is endowed phenom of triboelectrification, which was constructed as a negative influence in past, the positive and useful value in more applications. For example, this waterproof textile-based TENG is able to harvest universal low- and random-frequency mechanical energy and power up the personal electronics such as the light emitting diodes or charging the capacitors. The maximum output by raindrop can reach up to 1900 V/m2, 160 μA/m2, and 20 μW/m2; for wind, the output can approach to 2000 V/m2, 150 μA/m2, and 70 μW/m2; by human motion, the output can reach up to 300 V, 40 μA, and 1 mW. Furthermore, by integrating with microcomputer system for data acquisition and processing, the waterproof textile-based TENG was demonstrated as the self-powered sensor for actively human-interactive interfaces and combining with the wireless transmitter, which was able to remote manipulation computer for playing music. It is believed the waterproof textile-based TENG can be beneficial for the development of wearable electronics and smart clothing.
