Abstract
An integrated sensory actuator () which uses an electroactive polymer is provided. The sensory actuator is comprised of an actuating member () made of an ionic polymer-metal composite; a sensing member () made of a piezoelectric material; and an insulating member () interposed between the actuating member and the sensing member. The sensory actuator may further include a compensation circuit adapted to receive a sensed signal from the sensing member and an actuation signal from the actuating member and compensate the sensed signal for feedthrough coupling between the actuating member and the sensing member.
