Abstract :
In this study, piezoelectric energy harvesting device using lead-free [(Na0.5K0.5)]0.97(Nb0.96Sb0.04)O3 piezoelectric ceramics and rectifying circuit for energy harvesting were fabricated and their electrical characteristics were investigated. When the mass load was 2.4 g and the frequency of vibration generator was 62 Hz, output voltage of piezoelectric harvesting device indicated about 4.32 Vrms suitable for application as the electric power source of USN (ubiquitous sensor network) sensor node.
