Liquid‐Metal‐Based Stretchable Triboelectric Nanogenerators for Flowing‐Liquid‐Based Energy Harvesting and Self‐Powered Sensor Applications

Abstract: In this paper, a liquid‐metal‐based triboelectric nanogenerator (LM‐TENG) is proposed for harvesting energy from flowing water and self‐powered flow sensor applications. The proposed LM‐TENG mainly consists of a Galinstan working electrode that is encapsulated in a polydimethylsiloxane friction layer. The triboelectric performance of the LM‐TENG is optimized as a function of flow rate and frictional layer thickness. The output performance of the optimized LM‐TENG (6.2 V and 3.6 µA) is superior to that of the c… Show more

“…Hence, L-S TENGs have the potential to be used as energy-harvesting devices [12] that convert various forms of mechanical energy, such as rain droplets [13][14][15], sea waves [16][17][18][19], and human kinetic energy [20][21][22], into electrical energy. Furthermore, they can also be applied in various fields 2 of 13 such as flexible wearable technologies, self-powered sensing [23][24][25][26], and electrochemical protection [27].…”
