Biomimetic Device by Polymer Actuator

Abstract

A perfluorocarboxylic acid membrane chemically-plated with gold bends under electric stimili in water. Using the composites, it is made a biomimetic micro actuator having large displacement and uniquely controllable motion. Complex biomimetic motion can be simulated and controlled by type of electrical stimulation, and have great flexibility in motional response depending on the incorporated cation. The principle is currently being extended to a tubular form with quadrupolar directional control for medical applications. Using a simple joystick, this arrangement may serve as a superior active catheter for in-vivo surgery, e.g., in treating brain aneurysm.
