Abstract

In this study, piezoelectric energy harvesting device using lead-free [(Na_0.5K_0.5)]_0.97(Nb_0.96Sb_0.04)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 V_rms suitable for application as the electric power source of USN (ubiquitous sensor network) sensor node.
