March GGPF Dinner Lecture:

Michael's at Shoreline

"Electroactive Polymers:
Artificial Muscles and More"

Roy Kornbluh
SRI International
Menlo Park

Abstract:

Electroactive polymers (EAPs) offer the potential to
overcome limitations of traditional smart material
and transducer technologies. A particularly promising
class of EAP is dielectric elastomers. Dielectric
elastomer transducers are rubbery insulating polymer
materials with compliant electrodes that have a large electromechanical response to an applied electric field. The technology has been developed to the point where outstanding performance has already been
demonstrated: for example, the strains and elastic
energy corresponding to an applied electric field is
larger than that observed in any other field-activated materials, including the best piezoelectrics. Strains of over 300% also have been demonstrated: dielectric elastomers have also shown potential for use as large- area "skins" and as monolithic substrates on which many individually addressable areas can be patterned. Because of their unique characteristics and expected low cost, dielectric elastomer transducers are under development in a wide range of applications including multifunctional muscle-like actuators for biomimetic robots, microactuators for MEMS, smart structures, conformal loudspeakers, haptic displays, shoe-mounted generators for harvesting the energy of walking, and replacements for electromagnetic and pneumatic actuators for industrial applications. The dielectric elastomers have shown unique performance in each of these applications; however, some further development is required before they can be integrated into products and smart materials systems. Among the many issues that may ultimately determine the success or failure of the actuation technology for specific applications are the durability of the actuator, the operating voltage and power requirements, and the size, cost and complexity of the required electronic driving circuitry.

The talk will describe the principle of operation,
show the performance of various polymer materials and
highlight projects in a variety of applications. A
live demonstration will be performed.

Speaker background:

Roy Kornbluh is a Senior Research Engineer at SRI International, where he has been involved with several projects relating to the development of electromechanical devices and systems as a member of the Advanced Automation Technology Center. These projects have included the development of a tonometric blood pressure monitoring instrument and automated mail handling systems. For the past seven years, he has focused on the development of electroactive polymer transducers for a variety of commercial and government applications. Roy has authored more than 20 published papers and journal articles. He holds five patents with several more pending in the area of electroactive polymers. Prior to arriving at SRI, Roy received his Masters degree in mechanical engineering from the Massachusetts Institute of Technology and his Bachelors in mechanical engineering from Cornell University. Roy serves on the program committee for the SPIE Conference on Electroactive Polymer Actuators and Devices, Actuators 2002 Conference and IASTED Conference on Robotics and Automation.
