Paper Abstract

Compact sensing schemes are desirable for feedback control of ionic polymer-metal composite (IPMC) actuators in their targeted bio, micro, and nano applications. In this paper, a novel integrated sensory actuator with both position and force feedback is designed by combining IPMC with polyvinylidene fluoride (PVDF) films. The design adopts differential configurations for both the sensor-actuator structure and the sensing circuit, and thus eliminates capacitive coupling between IPMC and PVDF, minimizes the internal stress at bonding interfaces, and enables excellent immunity to thermal and electromagnetic noises. Closed-loop position control of the IPMC output is demonstrated together with simultaneous tip force measurement, based upon the integrated PVDF position and force sensors.
