  • INTEGRATED ACTUATOR SENSOR STRUCTURE
    Publication number: 20100109595
    Abstract: An integrated sensory actuator (10) which uses an electroactive polymer is provided. The sensory actuator is comprised of an actuating member (12) made of an ionic polymer-metal composite; a sensing member (14) made of a piezoelectric material; and an insulating member (16) 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.
