In this work, a hybrid energy harvester is proposed to broaden the working bandwidth of vibration energy harvesting. This design consists of two piezoelectric polyline beams standing with a gap distance, of which one is bonded with a piezoelectric patch and covered by an electret layer, while an ele...
