Outline of Final Research Achievements |
We addressed multilayer depositions of Pb(Zr,Ti)O3 (PZT) thin films. The multilayer structures up to four PZT layers were successfully fabricated. The most important advantages of the multilayer piezoelectric thin films is very low driving voltage and large deformation for actuator applications. Several MEMS (MicroElectroMechanical Systems) applications of the multilayer PZT thin films were developed in order to validate the applicability to the batch fabrication and the effectiveness of the multilayer structures. pMUT (piezoelectric Micromachined Ultrasound Transducers) with four layers of PZT thin films were developed. It was proved that the device could the high power transmission is available with very low driving voltage.
