We presented two new types of fabric-based triboelectric energy harvesters, which were constructed from conductive textiles and fibers as the conducting electrode and soft elastic polymer as the triboelectric material. The energy-harvesting fabrics can harvest human-motion energy through contact with skin. Its capability to harvest different kinds of human motions, including the movement of joints, walking, tapping, etc., was demonstrated. By integrating with clothing, we produce a power insole which can extract walking energy and light up light-emitting-diodes without the need of batteries. Furthermore, we applied a self-powered system to safety vest and commercial watch, which shows the promising application in smart clothing, and wearable electronics. This newly-designed large-area and stretchable energy-harvesting textile was demonstrated for the first time. The generating electric output reached up to 200 V and 200 μA.
The presented clothing-based energy harvest shows the potential to scavenge energy anytime and anywhere.
