Abstract

Using Aerosol Deposition Method it is possible directly deposited PZT 1~100-micron-thick films on different kinds of substrates. The mechanical, and piezoelectric properties of such piezoelectric films allowed applying it to the microactuator fabrication. In this presentation, 10-μm-thick PZT film was directly deposited on the stainless steel. After annealing and poling of PZT, the fatigue of such actuator was investigated applied bipolar electrical field of 30 kV/cm keeping actuator temperature at 100°C. After 10⁹ cycles changing in the vibration amplitude was not observed, as well as the actuator tip’s shift. Applications of such actuator for preside positioning of hard disk drive are discussed.
