A new actuator device is proposed using semiconductive ferroelectric ceramics. This device is a single-plate actuator capable of bending equivalently to a bimorph. A significant difference is simple structure named as a 'monomorph' as compared with a multi-stacked type in the bimorph. The bend in the monomorph device is realized by non-uniform electric field distribution in the piezoelectric ceramics, through the semiconductor-metal contact effect (Schottky barrier).
