The actuator consists of a PZT layer bonded to several other composite prepreg layers. In which, the interdigitated electrodes (IDE) are deposited on the surfaces of the PZT material. The PZT layer is poled in-plane and operatedin the semi d33-mode. Since the d33 coefficient is normally twice of d31 value, the actuationperformance of d33-mode LIPCA is expected to be improved significantly. Performance predictions of the d33-mode LIPCA are done by using the finite element method with a coupled-field model. Design of the IDE system patterned on the PZT surfaces is optimized in a poling process analysis to achieve the highest portion of PZT material poled in the longitudinal direction. Effect of the design variables such as electrode width, gap between electrodes and applied voltage for poling process is also performed numerically.
