Abstract
New type piezoelectric bending actuators, monomorphs, originate basically from a metal- semiconductor contact (Schottky barrier) effect. This paper deals with a more sophisticated model, Metal-Insulator-Semiconductor (MIS) structure, to explain detailed monomorph characteristics. Furthermore, voltage versus current relation was measured on the actuator sample to obtain better understanding on the monomorph. The electric charge flow during half a voltage cycle is of the order of 2.6 C/m2, which is several times larger than the usual charge flow associated with the polarization reversal.Keywords
