其他摘要：In this work we present the analytical model and experimental results of a vibration energy harvesting device with a PZT piezoceramic sheet under vibration-based excitation. The voltage and electric power generation is presented for the first two modes and compared. Also, the consideration of a tip mass to improve the energy generation is discussed for the considered cases. Finally, some conclusions remarks are drawn which show the benefits and possible disadvantages of generating power for high frequencies.
