In this study, in order to develop the composition of ceramics capable of being sintered at low temperature with high piezoelectric properties, PZW-PMN-PZT system ceramics for piezoelectric energy harvesting application were manufactured according to the amount of PZW addition. And also, their microstructural, dielectric and piezoelectric properties were investigated. At the sintering temperature of 930℃, a 5 ㏖% PZW substituted specimen showed a maximum value of density = 7.905g/㎤, kp = 0.585, d₃₃= 351 pC/N and Qm = 1,254, respectively.
