Micro Electromechanical Actuators Based on Conducting Polymers

There is considerable present interest in developing materials technologies suitable for the construction of electromechanical actuators having very small dimensions. The goal is to make the same transition in scale for mechanical devices which has already been made for electronic devices. Since this is a new area, many of the proposed applications are very futuristic — ranging from microrobotic devices for the exploration and repair of the human body to microscopic machines for the manipulation and alteration of micron dimensional objects. More concrete, shorter range goals include such devices as microtweezers, microvalves, micropositioners for microscopic optical elements, and actuators for micromechanical materials sorting (such as the sorting of biological cells).
