In this paper, model-based precision force and position control of an ionic polymer metal composite (IPMC) is presented. A 23.8 mm×3.4 mm×0.16 mm IPMC strip was used as an actuator in a cantilever configuration. Open-loop force and position responses of an IPMC are not repeatable, and hence closed-loop precision control is of critical importance to ensure proper functioning, repeatability and r...

SUMMARY Ionic polymer metal composites (IPMC) have been widely investigated as newly-emerging materials for transducer applications due to their good performance, such as low weight, good flexibility and large strain. A bio-inspired design was described and applied to build 3-D papillae dome structure for vectorial tactile sensors. INTRODUCTION The electrical-chemical-mechanical effect in ionic...

Robotic devices are traditionally actuated by hydraulic systems or electric motors. However, with the desire to make robotic systems more compact and versatile, new actuator technologies are required. In this paper, the control of ionic polymer metal composite actuators is investigated from a practical perspective. The actuator characteristics are examined though the unblocked maximum displacem...

Novel hand-held optical coherence tomography (OCT) probes with polymer cantilevers have been developed for clinical oral and skin imaging. An electroactive ionic polymer-metal composite cantilever was used to generate 3-mm transverse scanning movement of an optical fiber with applied 2-V linear alternating voltage at 1 Hz. Low driving voltage ensures safety. Two different optical designs achiev...

This paper presents an integrated sensor/actuator device with multi-input and multi-output designed on the basis of a standard control representation called a distributed port-Hamiltonian system. The device is made from soft material called an ionic polymer-metal composite (IPMC). The IPMC consists of a base film of a polyelectrolyte gel and a double layer of plated metal electrodes. The electr...
