Wearable electrode-free triboelectric generator for harvesting biomechanical energy

This article addressed an electrode-free triboelectric generator (e-free TEG) for scavenge biomechanical energy from human motions. By employing human body as natural electrode, no fabricated electrode is needed and output can be obtained from any part of human body. Under normal walking, an output voltage of 810 V is achieved and charge of over 550 nC is transferred in one step. Through a watch as the output node, 76 blue LEDs with characters of “PKU” are lighted.160
