Numerical analysis of a Ni-PZT stacked piezoelectric micro actuator is investigated for the prediction of mechanical behavior as a preceding research for the manufacturing of three dimensional micro structures. Finite element method is adopted to examine the simulation of a piezoelectric actuator according to applied direction of voltage, by researching displacement characterization of piezoelectric material through piezoelectric theory. PZT-4 is selected as a piezoelectric material. And bimorph finite element modeling is employed to study the response of Ni-PZT bi-layered micro actuator under the various input voltages. The results are presented as maximum displacement values under each applied voltages. Maximum displacement of 0.71μm at 60V is obtained.
