Dr. Yoseph Bar-Cohen
Dr. Yoseph Bar-Cohen is a physicist specializing in
electroactive materials/mechanisms and ultrasonic NDE. He is a Senior
Research Scientist and Group Supervisor, Advanced Technologies and the
Nondestructive Evaluation and Advance Actuators (NDEAA) Lab at the Jet
Propulsion Laboratory (JPL). The
NDEAA lab, which he established in 1991, has been responsible for a series
of innovative concepts and mechanisms for planetary explorations, medical,
commercial and other applications. Dr.
Bar-Cohen is a Fellow of two technical societies: SPIE and the American
Society for Nondestructive Testing (ASNT).
From Nov. 2009 to Sept. 2011,
he served as the Chair of the JPL’s Senior Research Scientists
Council. He made two notable discoveries of
ultrasonic wave phenomena in composite materials: the polar backscattering (1979)
and the leaky Lamb waves (LLW) (1983).
He received his Ph. D. in Physics (1979) and M.Sc. in Materials
Science (1973) from the Hebrew University, Jerusalem,
Israel. Currently, he
is responsible for developing ultrasonic drills, piezoelectric motors,
ultrasonic NDE and health monitoring methods, haptic interfaces,
electroactive polymer (artificial muscles) based mechanisms, and high power
ultrasonic techniques. The
drill and the electroactive polymer related activity were selected as NASA
and JPL Technology Spotlights. His
prior affiliations include Israel Aircraft Industry (1971-1979), NRC
Postdoc at AFML (1979-1980), SRL (1980-1983) and McDonnell Douglas
Corp. (1983-1991). His scientific, engineering and technology
accomplishments have earned him two NASA Honor Award Medals - NASA
Exceptional Engineering Achievement Medal (2001), and NASA Exceptional
Technology Achievement (2006), two SPIE’s Lifetime Achievement Awards – NDE
(2001) and Smart Materials and Structures (2005), the ASNT’s 2002 Lester
Honor Lecture Award, the 2006 ASNT Sustained Excellence award, the 2007
SPIE President’s Award as well as many other honors and awards.
His initiatives and proactive efforts in the area of Electroactive
Polymers led to the SPIE’s
EAPAD annual conference (which he has been chairing since 1999), the WW-EAP
Newsletter, and the WW-EAP Webhub. This
website is part of his JPL's NDEAA website that received over
million total hits in about 18-months (from January 1, 2000 to July 2 2001). The highest hits/day was
recorded on March 9, 2005, with 9063 total hits and 3626 unique hits. Moreover, the most comprehensive book
on the subject of EAP, for which he is the Editor and co-author, was
published in March 2001 by SPIE Press.
The 2nd edition of this book was published in March
2004. Also, he co-editing a book
that is entitled “Biologically-Inspired Intelligent Robots” examining the
scientific and engineering states as well as the future possibilities of
making robots based on these materials.
His edited and coauthored book entitled “Biomimetics – Biologically
Inspired Technologies” that provides a high level approach to this
topic. This book was published by
CRC Press in November 2005. In an
effort to promote rapid advances in the development of EAP, Dr. Bar-Cohen
posed in 1999 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. He held
the first armwrestling match between EAP actuated
robot and human on March 7, 2005 as part of the SPIE Annual International EAPAD
Conference.. Three arms wrestled
with a high school female student (she is now a Caltech student) and she
won against all of them. Even though
the arms lost the contest, this was a major milestone for the field.
He made significant
contributions to NDE of composites and bonded solids as well as aging
aircraft structures. He led the
development of a crawler, known as MACS (Multifunctional Automated Crawling
System) that can serve as a robotic platform for PC board base
instruments. As a follow-on effort,
he edited and co-authored an ASNT book on the subject of robotics for NDE,
which was issued in April 2000.
Other contributions include real time monitoring of composites
curing, broadband transducers, a LLW device for nondestructive
determination of elastic properties of composites and a catheter-based
Bar-Cohen’s research and accomplishments with his teams received extensive
media coverage including NASA Press Releases, JPL's Universe, and media
articles in daily newspapers (Diariovasco (Spain),
Haaretz (Israel), LA Times, Maariv
(Israel), Newsday, Newsweek Pasadena Start News, The Sunday Times, Yediot Aharonot (Israel),
etc.), magazines (Assistive Technologies, Aerospace America, Aviation Week,
Business Week, Computerworld (Switzerland), Discover, EE Times, International
Journal of Advanced Robotic Systems, New Scientist, Newsweek, Smart
Business, Orthotics and Prosthetics Business News, Poptronics,
Popular Science, Rosh Gadol (Israel), Scientific

technically related websites (Discovery Channel, Natural History, MSNBC,
RobotBooks.com, Nando Times News, etc.), as well
as radio (NPR-All Things Considered, BBC, Voice of America, Austria’s FM4, etc.)
and TV interviews. Dr. Bar-Cohen is
listed on over 34 Who’s Who Biographic Directories and in the Nov. 2001
issue of Tech Briefs he was featured as a Who’s
Who in NASA. For his
contributions to the field of electroactive polymers, Business Week named
him, under the category Gurus of Technology, as one of “Five
People Pushing Tech's Boundaries” and “The
Brain behind Plastic Muscle”; Popular Science (mirrored
by CNN) named him the “Artificial
Muscle Man”; SPIE’s OE magazine described him as “redefining
robotics” and Scientific American described him as the “unofficial
coordinator” of the field of EAP.
He made about 360 publications, numerous presentations at national
and international conferences, Chaired/CoChaired 44
Conferences/Symposia, has 22-registered patents and (co)Editor/Co-author of
7 books (with one in 2nd edition) and 21 conference proceedings, 94 New

"I attribute my success to my
imagination, creativity and hard work; but above all it comes from good
collaboration with top experts worldwide. My idea of cooperative research
with interdisciplinary experts was adapted from the world of ants who
collectively are capable of performing impressive tasks that are far beyond
what they are expected to be able to do as individuals." Dr.
Bar-Cohen's quote from the article entitled "Redefining Robotics"
