Paper Abstract

The volume change that the conducting polymer polypyrrole (PPy) undergoes upon electrochemical oxidation and reduction can be used to make microactuators. We have made microactuators based on a PPy/Au bilayer. These actuators have been combined with other micromachined structures to make biomedical microdevices. Using an area of bilayers one can potentially arrest (nerve) fibers. They can also be used to close a micrometer sized cavity with a lid. In addition, we demonstrate a microrobotic arm that may be developed for the manipulation of small particles.
