Abstract

Triboelectric nanogenerators (TENG) harvest energy based on contact electrification. Due to the large and replenishable contact interfaces in liquid-liquid (L-L) systems, L-L TENG promises improved efficiency in charge transfer. However, the limited understanding of L-L contact electrification mechanisms hinders its optimization. In this work, we investigate the mechanisms in various L-L systems and find that multiple mechanisms of L-L contact electrification would co-exist, while the dominant mechanism changes with materials. A microfluidics-based L-L TENG with optimized materials and structures is accordingly demonstrated to harvest energy from rainwater, highlighting the promise of microfluidic system in distributed energy and passive sensor. © (2022) by Chemical and Biological Microsystems Society All rights reserved.
