Dr. Yoseph Bar-Cohen

Biography

 

Dr. Yoseph Bar-Cohen is a Senior Research Scientist and the supervisor of the Advanced Technologies Group (x355N) as well as in-charge of the Nondestructive Evaluation and Advance Actuators (NDEAA) Lab, which he has established in 1991. He is a physicist specializing in electroactive materials/mechanisms and biomimetics (also known as Smart Materials and Structures) as well as ultrasonic Non-Destructive Evaluation (NDE).  He received his Ph. D. in Physics (1979) and M.Sc. in Materials Science (1973) from the Hebrew University, Jerusalem, Israel.  Under his leadership many innovative concepts and mechanisms were initiated, analytical modeled, developed, and tested for planetary exploration, commercial, medical, 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).  Currently, he is responsible for developing ultrasonic drills and planetary samplers, wireless acoustic mechanical feedthroughs, piezoelectric motors, ultrasonic NDE and health monitoring methods, haptic interfaces, electroactive polymer (artificial muscles) actuated mechanisms, and high power ultrasonic techniques.  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 and leadership 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 and authoritative book on the subject of EAP, for which he is the Editor and co-author, was published in March 2001 by SPIE Press.  Since the first edition run out, he made extensive updates to this book and published in 2004 the 2nd edition.  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” and “Biomimetics: Nature-Based Innovation” that provide a high level approach to this topic.  This books was published by CRC Press in 2005 and 2011, respectively.  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 This arms lose in the contest highlighted the complexity and enormity of the challenge that he posed and it attracted enormous professional and public attention to the field.  The graphic representation, which he created to illustrate the arm-wrestling challenge, has become the icon of the field of EAP in technical presentations worldwide.

 

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 acoustic microscope.

 

Dr. 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), Glendale News Press, Globes (Israel), 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 American, Time Magazine, Tech Directions, STROM (Switzerland), etc.), 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 34 Who’s Who Biographic Directories and his brief bio is listed on Wikipedia with links to his websites.  Also, the Nov. 2001 issue of Tech Briefs featured him 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 over 360 publications, hundreds of presentations at national and international conferences (including many Plenary, Keynote and Invited papers), (co)Chaired 45 national and international Conferences/Symposia, (co)edited/(co)authored  8 books, served as the Editor of 24 conference proceedings, and (co)authored 110 New Technology Reports (NTR).  His innovation is documented in 25 registered patents, 6 submitted patent disclosures, 13 Provisional Patents, 110 New Technology Reports, 73 Class 1 NASA Tech Brief Awards, and 14 NASA Board (Space Act) Awards.  Moreover, he is a member of the

"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" in Member Profile of the month, OE Magazine, March 2003.
