可穿戴电子产品引领着下一代传统的个人电子产品。然而，他们的传统电池需要经常充电或更换，这极大地限制了可穿戴电子产品的发展。因此，一种能够就地收集生物机械能以连续地为可穿戴电子设备供电的可穿戴电源是非常需要的。在这项工作中，我们首次报道了一种基于高疏水性的纳米纤维聚四氟乙烯（PTFE）聚合物的可水洗织物结构单电极摩擦电纳米发电机（TS-TENG）。沾污的TS-TENG可以很容易、快速地用水洗干净。TS-TENG可以缝在衣服上，然后通过与衣服材料的摩擦有效地将机械能转化为电能。当人在行走或跑步时摆动手臂操作时，TS-TENG的输出电压和电流分别为1050 V和22 μA。这种产生的电能可以直接为夜行灯和数字手表供电，而不需要任何储能过程。这种TS-TENG的开发可以为开发自供电的可穿戴电子产品提供巨大的机会，因为它具有灵活性，透气性，可洗涤性，以及从人体运动中收集生物机械能的能力。
Wearable electronics guide the next generation of traditional personal electronics. However, their conventional batteries are required to be frequently charged or replaced, greatly limiting the development of wearable electronics. Thus, a wearable power source that can in situ harvest biomechanical energy to continuously power wearable electronics is extremely desirable. In this work, we report for the first time a washable textile-structured single-electrode triboelectric nanogenerator (TS-TENG) based on a nanofibrous polytetrafluoroethylene (PTFE) polymer with high hydrophobicity. A stained TS-TENG can be easily and quickly cleaned by washing in water. The TS-TENG can be sewed on clothes, and then it can effectively convert mechanical energy to electricity by the friction with the material of clothes. When operated by swinging arms while people are walking or running, the output voltage and current of the TS-TENG obtained were 1050 V and 22 μA, respectively. This generated electric energy could directly power a night running light and a digital watch without any energy storage process. The development of this TS-TENG could provide great opportunities for developing self-powered wearable electronics due to its flexibility, breathability, washability, and capability to harvest biomechanical energy from human motions.
