Developing flexible, lightweight and sustainable power sources is an important route to provide electricity for portable electronics. Here, we demonstrate a high-performance double-layer-stacked triboelectric textile (DTET) for harvesting human motion energy. Both the Ni-coated polyester conductive textile and the silicone rubber were adopted as effective triboelectric materials. A high output open-circuit voltage of 540 V and a short-circuit current of 140 mu A can be obtained from the DTET with the size of 5 x 5 cm(2), corresponding to a high peak surface power density of 0.892 mW/cm(2) at a load resistance of 10 MO. The output peak signal of the DTET can be used as a trigger signal of a movement sensor to design movement monitoring equipment. With only the energy harvested from walking, running or flapping, the DTET can directly light up 100 light-emitting diodes (LEDs) connected serially, and drive portable electronics, such as competition timer, digital clock and electronic calculator, which indicate the potential and broad application prospects in biological health monitoring, outdoor exploration, troop marching and portable electronics.
