Piezoelectric Actuator samples were fabricated using PMN-PT-PZ ceramics with Barium substitution, and the strain properties of them were investigated. The tartest Piezoelectric coefficient and electromechanical coupling coefficient were observed at the sintering temperature $1250^{\circ}C$, Barium 5mol%. In the case of Multilayered specimens, they showed considerable strain and small hysteresis than single round type.
