Abstract

In this paper, a 2-DOFs (two-degree-of-freedoms) right-angle-shape piezoelectric energy harvester is designed and analyzed for widening the operation bandwidth (-3dB bandwidth) of piezoelectric energy harvester in low frequency vibration environment. The finite element simulation results show that, the operation bandwidth of the optimized device comprises two operating frequency bands near the first resonant frequency 21.67Hz and second resonant frequency 48.75Hz, the operation bandwidth of two beams are 13.8Hz and 14.2Hz, the output- powers reach 25mW and 41mW respectively. It is demonstrated that the 2-DOFs right-angle-shape piezoelectric energy harvester which reduces each order natural frequency, increases the output-power density, and ensures the wide operation bandwidth, could be efficient and adaptive in low-frequency vibration environment.
