Biomedical Applications of Electroactive Polymer Actuators
John Wiley & Sons Ltd., 2009.
Electroactive polymers (EAP) are a family of "smart materials" that possess an attractive combination of
intrinsic electromechanical transduction capabilities with the mechanical flexibility, processing
versatility, and low cost that are typical of polymers. As a result, EAP actuators are being studied as
candidate materials for "artificial muscles". This book describes work toward biomedical applications of
the most technologically mature classes of EAP, namely polymer gels, ionic polymer metal composites,
conducting polymers, piezoelectric/electrostrictive polymers, and dielectric elastomer actuators.

Robots that swim in the bloodstream, scissors that take a biopsy from within a blood vessel deep inside
a kidney, tapping fingers that measure the hardness of cells to distinguish cancerous from normal
tissue, and smart pills that dispense drugs in concentrations that change with the body's needs -
these are among the future technologies that have been envisioned by engineers and doctors for
minimally invasively diagnosing and treating patients. However, working on the micro-scale like
this will require micro-scale tools (microelectromechanical systems, or MEMS). In this chapter, we review some of the exciting prototype micro-scale biomedical devices that have been demonstrated in the laboratory.

In many respects, conjugated polymers are well-suited for micro-electro-mechanical systems (MEMS) and other micro-devices. The versatility of function makes conjugated polymers potentially useful for micro-actuators, micro-sensors, and micro-energy sources (such as batteries). Furthermore, the speed of micro-sized conjugated polymer devices can be greatly enhanced over macro-scale devices since ion transport distances are small and surface areas are large. In addition, the wide range of patterning methods suitable for conjugated polymers enables straightforward micro-fabrication of these materials. This paper reviews the inherent advantages of conjugated polymers for micro-devices and describes some of the demonstration devices already constructed. Some future directions, including challenges and the possible development of nano-scale conjugated polymer devices, are also discussed.

Conjugated polymers actuators can be operated in aqueous media,
which makes them attractive for laboratories-on-a-chip and applications in
physiological conditions. One of the most stable conjugated polymers under
these conditions is polypyrrole, which can be patterned using standard
photolithography. Polypyrrole-gold bilayer actuators that bend out of the plane
of the wafer have been microfabricated in our laboratory. These can be used to
move and position other micro-components. We review the current status of
these microactuators, outlining the methods used to fabricate them. We describe
the devices that have been demonstrated as well as some potential future
