A bridge-shaped vibration energy harvester with resonance frequency tunability under dc bias electric field

HIGHLIGHTS

  • who: Guan Duan et al. from the School of Chemistry and Civil Engineering, Shaoguan University, Shaoguan, China have published the paper: A Bridge-Shaped Vibration Energy Harvester with Resonance Frequency Tunability under DC Bias Electric Field, in the Journal: Micromachines 2022, 1227 of /2022/
  • what: In this work, a new bridge-shaped PEH with a constrained double-end was proposed to further improve the bandwidth of the resonance frequency by tuning the DC electric field to piezoelectric elements.
  • how: The experiments were carried out to successfully verify the tunability of the resonance frequency . . .
