Abstract

We fabricated a spring-supported piezoelectric unimorph cantilever (SPUC) with enhanced energy-harvesting characteristics by using a 0.69Pb(Zr_0.47Ti_0.53)O₃–0.31Pb(Ni_0.6Zn_0.4)_1/3Nb_2/3)O₃ + CuO (0.5 mol%) thick film sintered at 950 °C; a spring having a spring constant of 14,320 N/m was used as the cantilever support. The SPUC could generate an output power as high as 29 mW with a spring constant of 14,320 N/m across a resistance of 150 kΩ; this corresponded to a power density of 34 mW/cm³. We, therefore, that the thus-fabricated SPUCs when supported by a spring can harvest increased levels of energy.
