An instantaneous discharging liquid-solid triboelectric nanogenerator (IDLS-TENG) with boosted peak power output

Abstract

Liquid-solid triboelectric nanogenerator (LS-TENG) has emerged as a powerful tool in energy harvesting and motion detecting. There is a recognized need for improving the power output and signal-to-noise ratio of LS-TENG. The instantaneous discharging mechanism of LS-TENG is studied and experimentally realized by a controllable switch structure in this paper. The peak short circuit current and peak power output (at 1 MΩ) are increased by over 26 and 1700 times, respectively, with respect to the control LS-TENG working in the single electrode mode. This research provides a fresh insight in designing sensors with high signal-to-noise ratio and energy harvestors that have a superior performance in driving devices with low load resistance.
