Abstract

Charged films with a cellular structure show pseudo-piezoelectric properties with high transducer constants. Measurements of the direct and inverse transducer constants, the thermal stability of the charge, and Young's modulus of such films are presented. The electromechanical response equations are derived for their operation as sensors and actuators. By assuming reasonable charge distributions and charge densities, the calculated transducer constants are in good agreement with the measured values. Both the measurements and the theoretical model show the reciprocity of the transducer operation.
