Abstract
Polypyrrole (PPy)-based microactuators hold a promise for a wide variety of engineering applications from robotics and
microassembly to biosensors and drug delivery systems. The main advantages of using PPy/Au actuator structures (vs
competing solid-state actuator technologies) include ease of fabrication, low actuation energy, and large motion range of
microactuators. We present advances in two areas of application - in the extended-life biosensor platform and in
micromixers.
