To compare with the doped PZT powder and don't doped PZT powder in the PZT thin film can be observed the material property and microstructure. The polarization(Pr) will descend because doping PZT powder in the thin film appears with the drawback type, The stress analysis result of the PZT thin film appears that the pyrochlore phase existence will make the piezoelectric property descend and residual stress increment. Use don’t doped PZT powder on the multilayer PZT thin film to develop Osteoblast-like cell(MG63). The cell were developed on the PZT thin film, through eight hours, one day, two days, four days, six days and eight days. The cell will proliferate and differentiate on the multilayer PZT thin film surface. The cell proliferation and division situation are more remarkable with time by calculation cell survives rate and cell activity. The multilayer PZT thin film will used in the biomedical science.
