    摘要： An active micro-force sensor is provided for use on a micromanipulation device. The active micro-force sensor includes a cantilever structure having an actuator layer of piezoelectric material and a sensing layer of piezoelectric material bonded together. When an external force is exerted on the sensor, the sensor deforms and an applied force signal is recorded by the sensing layer. The applied force signal is then fed back to the actuating layer of the sensor via a servoed transfer function or servo controller, so that a counteracting deformation can be generated by the bending moment from the servoed actuating layer to quickly balance the deformation caused by the external micro-force. Once balanced, the sensor beam comes back to straight status and the tip will remain in its equilibrium position, thus the sensor stiffness seems to be virtually improved so that the accurate motion control of the sensor tip can be reached, especially, at the same time, the micro-force can also be obtained by solving the counteracting balance voltage applied to the actuating layer.

    摘要： 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.
