摘要：
In this study, we have investigated 1-3 story structured piezoelectric energy harvesters based on lead zirconate titanate (PZT) multi-layered actuators. These piezoelectric energy harvesters were fabricated using Pb(Zr,Ti)O-3 based ceramic actuators. The multi-layered PZT actuators were based on green sheets that were prepared by a tape casting process. The ceramic actuators were attached on metallic electrodes with poled states. The structures were filled with polydimethylsiloxane (PDMS). The multi-layered piezoelectric energy harvesters were stacked as single-story structured, double-story structured, and triple-story structured devices, respectively. Generated output voltages, stored power, and maximum output power with various loads of the piezoelectric energy harvesters with various story structures were analyzed.
