Ultrastretchable Triboelectric Nanogenerators Based on Ecoflex/Porous Carbon for Self‐Powered Gesture Recognition (Adv. Mater. Technol. 9/2023)

Triboelectric Nanogenerators In article number 2201769, Huamin Chen and co-workers present an ecoflex/porous carbon-based triboelectric nanogenerator (TENG) that exhibits ultrahigh stretchability and high performance due to the appropriate conductive networks and strong trapping effect. Its performance just degrades about 30% at a stretching strain of 177%. The stretchable TENG array can recognize gesture signal of the finger to control mechanical hand, which demonstrates a promising potential in human-machine interaction.
