Abstract

In this paper, the optimal stackable piezoelectric power generation device and its rapid energy-saving system was designed and fabricated. In order to increase the efficiency of conversion power from piezoelectric device, three two-layer stackable piezoelectric power generation devices stacked in different geometric structures were arranged and compared for obtaining a greater created output power. Evidence shows that the sample No.3 could generate the highest output instantaneous power (4.132mW) than both of samples No.2 (2.852μW) and No.1 (1.897μW), which acts as the optimal structural design. Finally, by utilizing optimal of two-layered stackable piezoelectric power generation module combined with the single-level buck converter rapid energy storage system fabricated in this work, the Ni-MH battery with capacitance of 100mAh could be fully-charged within two hours.
