Polymer actuator


An actuator that uses polymer.

A polymer gel like polyvinyl alcohol contracts or swells at external stimuli such as hydrogen ion concentration, temperature, and electromagnetic energy. The property is used not only as an actuator , but also as a sensor. Polymer actuators can be applied to the robot hand, sensors, switches, and drug delivery system. Features of polymer actuators are: 1) System simplification by its multifunctionality, 2) Compactness, 3) Good moldability,4) Good biocompatibility.
