Abstract

A 0.69Pb(Zr0.47Ti0.53)O3-0.31Pb(Ni0.6Zn0.4)1/3Nb2/3)O3 +0.5 mol% CuO (PZCN) thick films were investigated for potential use in energy harvesting device applications. The PZCN thick films were fabricated by a conventional tape casting process and sintered at various temperatures. An excellent piezoelectric properties of d33 = 470 pC/N, ε33 T0 =1654, kp = 0.52 and d33 ⋅ g33 = 15,087 × 10−15 m2/N were obtained film sintered at 950 °C that this material as a energy density material. It was also demonstrated that a unimorph cantilever using the PZCN film could generate a significant power of 7.6 mW (1.05 mW/cm2) for high performance energy harvesters.
