Electroactive Polymers for Controlled Movement and Substance Release
Thu, 04/02/2009 - 5:33am
Micromuscle is an advanced, biocompatible electroactive polymer (EAP) that changes volume and other properties in response to an electrical stimulus and can be incorporated into medical devices. The technology enables both controlled movement of a device and the active controlled release of substances from a device. The controlled movement of Micromuscle EAP is characterized by the ability of the polymer to swell and contract in response to the application of a small electrical stimulustypically 1-2 Volts. An alternative feature of this characteristic is an electrical stimulus can begin a sequence of substance elution from the polymer.
