The 11th SPIE’s EAPAD Conf.


Session 3: EAP-in-Action Session

San Diego, CA, March 9, 2009

Moderator - Yoseph Bar-Cohen, JPL

3:10 to 4:30      Preparation for the EAP-in-Action Session

4:30 to 5:45      EAP-in-Action Session demonstrations


This Session, which is part of the 11th SPIE’s EAPAD Conference, is intended to turn the spotlight on Electroactive Polymers (EAP) materials, their capability, and their potential for smart structures.  New materials and applications are continuing to emerge and this is a great opportunity for the attendees to see state-of-the-art demonstrations of the unique capabilities of EAP as possible actuators-of-choice.  This Session offers a forum for interaction between developers and potential users as well as a "hands-on" experience with this emerging technology.  It was during this session that the first Human/EAP-Robot Armwrestling Contest was held in 2005. 

In 2009, we are going to have exciting demonstrations by 8 groups from the following countries: China, Italy, Japan, New Zealand, Switzerland, and the USA.  These demos will include various novel EAP actuators, prototypes and emerging products.
