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 twodoi:10.2991/cset-16.2016.40 fatcat:c6qvhkewfbdevaywdsmst4ctqu
