Abstract :
Monolithic Multi-Material piezoelectric-electrostrictive (PE-ES) composite actuators were developed by co-sintering of 0.65PMN?0.35PT and 0.9PMN?0.1PT. The piezoelectric and electrostrictive ceramic powder were dry pressed into bi-layer disks with 1:1 ratio. The bi-layer composites were co-sintered and then poled. The monolithic bi-layer PE-ES composites (either flat or dome) were used to fabricate cymbal actuator. Experimental results indicate that uncapped bi-layer dome shaped actuators provide strong interface and exhibits peak displacement as high as 14 #m at 10 kV/cm. Cymbal actuators fabricated using such dome bi-layer composite results in amplified-displacement with a peak value of 25 ?m at 10 kV/cm.
