Energy harvesting characteristics of unimorph cantilever generator using 0.69Pb(Zr0.47Ti0.53)O3-0.31Pb(Ni0.6Zn0.4)1/3Nb2/3)O3 + 0.5 mol% CuO (PZCN) thick films under various sintering conditions

A 0.69Pb(Zr 0.47 Ti 0.53 )O 3 -0.31Pb(Ni 0.6 Zn 0.4 ) 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, ε 33 T / ε 0 =1654, k p = 0.52 and d 33 ⋅ g 33 = 15,087 × 10 −15 m 2 /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/cm 2 ) for high performance energy harvesters.
