- Abstract
- The Ferroelectric and piezoelectric properties of 0.72Pb(Z(r0.47)Ti(0.53))O-3-0.28Pb[(Zn0.45Ni0.55)(1/3)Nb-2/3]O-3 (PZT-PZNN) piezoelectric thick films were investigated for application to energy harvesting devices. The PZT-PZNN thick films were fabricated by a conventional tape casting process. The sintered PZT-PZNN thick film was highly dense and flat when the annealed temperature was 1100 degrees C. It exhibited substantial ferroelectric and piezoelectric properties of P-r = 20.6 mu C/cm(2), d(33) = 370 pC/N, epsilon(T)(33)/epsilon(0) = 1185, and k(p) = 0.44. Moreover, its d(33) . g(33), which can characterize high energy density material, is as large as approximately 13050 x 10(-15) m(2)/N. Therefore, the PZT-PZNN thick film can be a potential piezoelectric material for application to energy harvesting devices. (C) 2012 The Japan Society of Applied Physics
