The JPL's Nondestructive Evaluation and Advanced Actuators (NDEAA) Technologies lab
was established by Dr. Yoseph Bar-Cohen
in May 1991 and it is part of his JPL's Advanced Technologies Group. The Group members are
Dr. Jack B. Aldrich ,
Dr. Mircea Badescu,
Dr. Xiaoqi Bao,
Dr. Zensheu Chang, and
, Dr. Stewart Sherrit.
Other scientists that are working in his NDEAA Lab include
Dr. Shyh-Shiuh Lih. Also, thru the JPL
Educational Outreach Program
professors, visiting scientists and students
are participating in various studies at this lab.
The NDEAA lab is listed as one of the
6 sites of JPL's technology website and it is involved with
innovative research and development
(R&D) for space applications and technology transfer to other fields. The topics of R&D include novel
actuators (mostly using electroactive ceramics and polymers), transducers, sensors, robotic mechanisms and NDE methods. The group conducts analytical modeling, mechanisms development,
performance testing and characterization as well as analysis that involve mechanical, electrical,
magnetic and thermal parameters and interactions.
Between Jan. 1, 2000 and Jul. 2, 2001, this NDEAA webhub had 1,000,007
(crossed the one million) total hits with 87,082 unique hits and by Sept. 3, 2001 it
crossed the one hundred thousand (100,006) unique hits.
The highest hits per day was recorded on March 9, 2005, where 9063 total hits and 3626 unique hits were recorded.
This lab has been the subject of
many articles in the news media.
The NDEAA lab is involved with a broad range of R&D topics as described in the following clickable icons.

The developed mechanisms are driven by elastic waves, mechanical vibrations and/or electroactive
materials. Examples of these mechanisms include ultrasonic and surface acoustic wave motors
and piezoelectric pumps that are driven by traveling flexural waves. Recently, an ultrasonic/sonic driller/corer
(USDC) was developed and shown to have enormous potential for sampling, deep drilling, probing, sensing and in situ
analysis making it a Lab-on-a-Drill. In parallel, electroactive polymers are being investigated for use as
actuators (artificial muscles). Other technologies that are being explored include Haptic
interfaces for robotics and Human Muscle Enhancers -- high power ultrasound for medical treatment,
ferroelectric source that generates various radiations and charged particles, biomimetic technologies
and geophysical probing using elastic waves. In addition to planetary applications,
these devices and mechanisms have potential terrestrial applications for medical, commercial, and others.
These efforts involve technical cooperation with scientists and engineers at various universities,
research institutes, medical centers and industry in the USA and internationally.
Further, the Nov. 2001 issue of the NASA Tech Briefs covered Dr. Bar-Cohen and NDEAA in a
"Who's Who in NASA" article.
