Abstract

Ionic Polymer Metal Composites (IPMCs) have several unique characteristics such as, low driving voltage, no moving parts, etc., that allow the material to fulfill specific needs for medical device applications. However, there are numerous challenges that must be addressed in order to utilize IPMC in medical devices. The research presented is a culmination of efforts that address a number of these issues; such as electrolysis of water, safety concerns, material characterization and in vitro testing. Work on IPMC development has raised the threshold of the electrolysis of water during actuation from 2.35 V to 2.46 V in Tyrode's solution. The problem of back relaxation under DC excitation has been reduced. To ensure accurate measurements of IPMC performance, for medical applications, it is imperative that the appropriate in vitro testing conditions are chosen, such details are discussed. Material characterization techniques developed and used by Pavad Medical, which are based on medical device needs, are also highlighted.
