Stretchable triboelectric generator, stretchable electricity storage device, and wearable electronic device

Abstract

Disclosed herein are a stretchable triboelectric generator, a stretchable electricity storage device and a wearable electronic device. The stretchable triboelectric generator comprises a first stretchable triboelectric generation part comprising a first fabric layer and a first friction layer on the first fabric layer and a second stretchable triboelectric generation part comprising a second fabric layer and a second friction layer on the second fabric layer. The stretchable electricity storage device comprises at least one of a stretchable battery or a stretchable supercapacitor. The stretchable electricity storage device may be connected to the stretchable triboelectric generator and may store electricity generated by the stretchable triboelectric generator. The wearable electronic device comprises the stretchable triboelectric generator, the stretchable electricity storage device and a sensor connected electrically to at least one of the stretchable triboelectric generator or the stretchable electricity storage device to sense vital signs, bio signals, or body's movement changes.
