In order to make functionally graded piezoelectric materials, a forming process using electrophoretic deposition (EPD) was developed. Two types of PNN-PZT calcined powder were used as materials. The piezoelectric ceramics could be deposited on copper electrode immersed in the ethanol suspension with calcined PNN-PZT powder. The 3-point bending tests was carried out on sintered bilayer material samples formed by EPD. It was found that the strength characteristics of the bilayer material was similar to that of the weaker single layer material. Multilayer piezoelectric ceramics were formed by EDP using several suspensions in which mixing ratios of two kinds of ceramics were changed. On the multilayer material, it was confirmed that the mixing ratio of the two piezoelectric ceramics gradually changed by XRD. The cantilever type monomorph actuator with multilayer piezoelectric ceramics was made by using EPD and confirmed its driving under alternating voltage.
