Abstract

The piezoelectric material is the key of preparing the energy harvesting device with high performance as a kind of core functional material for environmental vibration energy harvesting device. The 0.7Pb(Zr _0.51Ti _0.49) _0.99O ₃ - 0.3Pb(Zn _1/3Nb _2/3)O ₃(PZT-PZN) piezoelectric ceramic were prepared by the two step synthetic method. The effect of different doped mass contents of La ₂O ₃ on the crystallographic phase and electromechanical properties have been studied. The results showed that the piezoelectric coefficient d ₃₃, the electromechanical coupling factor (k ₃₁, k _p) and the dielectric constant ε _r have been improved with little La ₂O ₃ dopants. The PZT-PZN ceramic sintered with 4% La ₂O ₃ doping possesses the optimum propeties of d ₃₃=560 pC/N, k ₃₁=0.376, k _p=0.642, s ₁₁ ^E = 16.5×10 ^-12m ²/N, ε _r=3125.
