This homepage provides links to various electroactive polymer (EAP) websites worldwide and it is maintained by the JPL's NDEAA Technologies Lab. For background information please see a lecture on video entitled "Electroactive Polymers as Artificial Muscles”. The field of EAP is part of the broader field of biomimetics
Note: The graphics on this
website is clickable. The graphics of the two EAP platforms are linked to
videos that require QuickTime.

In 1999, Dr. Bar-Cohen posed
a challenge to the worldwide research and engineering community to develop a
robotic arm that is actuated by artificial muscles to win an armwrestling
match against a human opponent. The first Armwrestling Match between EAP
actuated Robot and Human (AMERAH) was held on March 7, 2005 as part of the 2005
SPIE Annual International EAPAD
(EAP Actuators & Devices) Conference. This match was organized with
assistance from the United
States ArmSports who provided the table for the
match. There were three
participating organizations including Environmental Robots Incorporated
(ERI),
Some of the applications that are being considered include Haptic/Tactile Interfaces and particularly Active Braille Display. Another development is the first commercial product and it is a fish robot, and it was announced by EAMEX, Japan, at the SPIE's EAPAD 2003 Conference.

These tables and charts are based on preliminary data. We would like to
encourage the research community to challenge the data and help us make it as
accurate as possible.

Terminology
EAP
- general term describing polymers that respond to electrical stimulation
Electronic
EAP - polymer that change shape or dimensions due to migration of
electrons in response to electric field (usually dry)
Ionic EAP - polymer that change shape or
dimensions due to migration of ions in response to electric field (usually wet
and contains electrolyte)
Electrostriction
- the none linear reaction of ferroelectric EAP (relating strain to
