Study of Electrode Design and Inclination Angle for Superior Droplet-Driven TENG Performance

Nano Letters, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 25, 2024

The urgent need for efficient water energy harvesting has led to the development of triboelectric nanogenerators (TENGs). In this study, considering droplet spreading dynamics and capacitive effects in a droplet-driven TENG (DD-TENG) device, an inverse relationship between width top electrode output voltage was derived first time through circuit model experimentally verified. Additionally, key performance parameters were optimized, including types widths electrodes, dropping height, inclination angle solution types. A nonmonotonic device established. Under optimal conditions, DD-TENG achieved 1133% increase compared that without electrode. power density reached 1265 mW·m–2, which is among state-of-the-art devices. These findings provide valuable insights improvement DD-TENGs.
