Harmonic-resonator-based triboelectric nanogenerator as a sustainable power source and a self-powered active vibration sensor

Jun Chen et al. Adv Mater. .

Abstract

A harmonic-resonator-based triboelectric nanogenerator (TENG) is presented as a sustainable power source and an active vibration sensor. It can effectively respond to vibration frequencies ranging from 2 to 200 Hz with a considerably wide working bandwidth of 13.4 Hz. This work not only presents a new principle in the field of vibration energy harvesting but also greatly expands the applicability of TENGs.

Keywords: energy harvesting; harmonic resonator; nanogenerator; triboelectric effect; vibration sensor.
