2003 EAPAD Conference,

EAP-in-Action Session, Held on March 3, 2003, 5:00 to 5:40 PM, in San Diego, California, USA


MODERATOR: Yoseph Bar-Cohen, Jet Propulsion Laboratory, Chair, EAPAD Conference


This Session that is held annually as part of the SPIE’s EAPAD conference is intended to turn the spotlight on Electroactive Polymers (EAP) materials and their applications as well as increase the recognition of their potential for smart structures.   New materials and applications are continuing to emerge and this session is intended to provide the attendees an opportunity to see a demonstration of EAP materials in action.  This Session offers a forum of interaction between the technology developers and potential users as well as a "hands-on" experience with this emerging technology.  It provides a great opportunity to see the capability of state-of-the-art of EAP as potential actuators-of-choice.  It is anticipated that the first Human/EAP-Robot Armwrestling Competition will be held is a future forum of this session.

VIDEO - Robotic Fish – the first commercial EAP-based product and a major milestone for the field - EAP actuators (1mm x 12mm is size) are responsible for the fish swimming and they are attached between the body and fish tail and fins. 

Kazuo Onishi and Shingo Sewa, EAMEX Corp– development of the high performance EAP actuator and the fish robots

DAIICHI KOGEI Corp – manufacturing and marketing

VIDEO - Microrobot, some microactuators, in-vitro surgery of blood vessel connector and short video of implantation surgery (on laboratory rats)..  A hands on non-functioning old microactuator samples will also be shown for actual size

VIDEO - Carbon Nanotubes EAP

The video will show the response to +2V square wave signal where the Nanotube film changes its shape.  The sample was tested using cyclic, differential, and normal signals showing a similar response.  During activation bubbles are seen emitted from the film and the presenters are concerned that the shape change is not an EAP behavior but a result of the bubbles emission.  When the film is placed in a strong organic base there is no movement in the potential range of -2V (< reduction potential for electrolysis in this base).

Sample - A gold plated Nanotube electrode in a three electrode system of a single compartment cell. The electrolyte is 2M Nano3 with platinum and an Ag/AgCl as the counter and the reference electrodes.
