Energy harvesting characteristics of unimorph cantilever generator using 0.69Pb(Zr0.47Ti0.53)O-3-0.31Pb(Ni0.6Zn0.4)(1/3)Nb-2/3)O-3+0.5 mol% CuO (PZCN) thick films under various sintering conditions

Abstract

A 0.69Pb(Zr0.47Ti0.53)O-3-0.31Pb(Ni0.6Zn0.4)(1/3)Nb-2/3)O-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 (33) = 470 pC/N, epsilon (33) (T) /epsilon (0) =1654, k (p) = 0.52 and d (33) a <...aEuro parts per thousand g (33) = 15,087 x 10(-15) m(2)/N were obtained film sintered at 950 A degrees 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(2)) for high performance energy harvesters.
