“…Punning et al 85 presented a novel design of a self-sensing actuator, which gave feedback of its own position where they showed the correlation between the surface resistance and the bending curvature because of the behavior of the surface electrodes i.e., the change of the surface resistance of the stretching side is greater than that of the corresponding unstretched surface. By comparing the voltage signal of the moving part of IPMC to the reference signals (fixed), the extent of bending was determined with respect to the straight IPMC sheet.…”

In this paper we present a comprehensive review of ionic polymer metal composite (IPMC) covering fundamentals of IPMC; from fabrication processes to control and applications. IPMC is becoming an increasingly popular material among scholars, engineers and scientists due to its inherent property of low activation voltage, large bending strain, i.e., transformation electrical energy to mechanical energy, and properties to be used as bidirectional material, i.e., it can be used as actuators and sensors. Among the diversity of electro active polymers (EAPs), recently developed IPMCs are good candidates for use in bio-related application because of their biocompatibility. Yet, the challenge remains in controlling a somewhat complicated material as mechanical, electrical and chemical properties interact with each other in the ionic polymer. Several IPMC fabrication processes, their mechanical characteristics and performance, a number of recent IPMC applications and pertaining mathematical modeling have been reported in this paper. Also we have attempted to present concisely the control of IPMC and effects of various factors in the performance of IPMC. The applications of IPMC have been growing, and recently more sophisticated IPMC actuator applications have been performed. This indicates that the IPMC actuators hold potential for more sophisticated control application. Extensive references are provided for more indepth explanation.

“…However, this approach is difficult to implement due to the very weak sensing signal compared to the actuation signal (millivolts versus volts) [1] and the nonlinear [25], dynamic [26,2] sensing responses. Punning et al proposed an integrated sensing strategy by exploiting the correlation between IPMC surface electrode resistance and the bending curvature [27,28]. This method relies on the assumption that the behavior of IPMC surface resistance is constant, which is often not true as the resistance varies with time 0924-4247/$ -see front matter © 2008 Elsevier B.V.
