Energy harvesting characteristics of unimorph cantilever generator using 0.69Pb(Zr sub(0.47)Ti sub(0.53))O sub(3)-0.31Pb(Ni sub(0.6)Zn sub(0.4)) sub(1/3)Nb sub(2/3))O sub(3) + 0.5 mol% CuO (PZCN) thick films under various sintering conditions

A 0.69Pb(Zr sub(0.47)Ti sub(0.53))O sub(3)-0.31Pb(Ni sub(0.6)Zn sub(0.4)) sub(1/3)Nb sub(2/3))O sub(3) +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 d sub(33) = 470 pC/N, epsilon sub(33) T / epsilon sub(0) =1654, k p =0.52 and d sub(33)g sub(33) = 15,08710 super(-15) m super(2)/N were obtained film sintered at 950 degree 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/cm super(2)) for high performance energy harvesters.
