The influence of a mechanical structure's volume increment on the volume power density(VPD)of triboelectric nanogenerators(TENGs)is often neglected when considering surface charge density and surface power density.This paper aims to address this gap by introducing a standardized VPD metric for a more comprehensive evaluation of TENG performance.The study specifically focuses on 2 frequency-up mechanisms,namely,the integration of planetary gears(PG-TENG)and the implementation of a double-cantilever structure(DC-TENG),to investigate their impact on VPD.The study reveals that the PG-TENG achieves the highest volume average power density,measuring at 0.92 W/m3.This value surpasses the DC-TENG by 1.26 times and the counterpart TENG by a magnitude of 69.9 times.Additionally,the PG-TENG demonstrates superior average power output.These findings introduce a new approach for enhancing TENGs by incorporating frequency-up mechanisms,and highlight the importance of VPD as a key performance metric for evaluating TENGs.
