Dr. Joseph R. Stetter’s
interests span analytical,
physical, and environmental chemistry with particular emphasis on
sensors, sensor arrays, biosensors, and electroanalytical chemistry.
Stetter, now president of KWJ Engineering Inc and Professor of
Chemistry at IIT, has held
positions of VP Engineering, Senior Research Chemist, Product Manager,
of Chemical Research, Section Manager, and Group Leader in industry,
and research institutions. In the 1970s, Dr. Stetter was Director of
at the Energetics Sciences Division of Becton, Dickinson, and Company
Fortune 500 company) and was responsible for the corporate direction
expansion of the research department. While at Becton, Dickinson, and
in the late 1970s, he developed the first diffusion sampled
sensors and introduced the earliest diffusion CO dosimeters in 1979.
then, diffusion sampling for electrochemical sensors has become the
standard for CO sensors and instruments. In addition, he developed a
solid-state gas sensor for carbon monoxide and an electrochemical SO2
and interfaced them to a GC. The electrochemical sensor for hydrazine
determination, developed by Dr. Stetter, is yet used today by USAF/SAC
While at the Argonne National Lab in suburban Chicago, Dr.
Stetter led the interdisciplinary team to develop the first operational
"sensor-array-based" instrument with pattern recognition. This
technology, developed during 1981-1984, received the IR-100 Award
the construction of the advanced "CPS-100" Hazardous Gas Monitor, and
is the world’s first “electronic nose” instrument contained in a camera
complete with sensor array, pattern recognition algorithm, and
system for sampling and readout.
Stetter founded and was president of Transducer Research, Inc.
[TRI] from 1983-1996 where he and co-workers continued to advance
sensors, incorporating new sensor technology to produce
sensors. Stetter’s innovative and tiny sensor designs used less than
300 uL of
electrolyte and were introduced by TRI in 1993. These first miniature
low-volume sensors then became standard in
the electrochemical sensor industry with other companies introducing
electrochemical sensors about three year later. This TRI sensor
allowed TRI, TSI, and others to make diminutive sensor probe designs,
by TRI for real-time ppb-level NO2 measurement for human exposure
(SONY Walkman size). Since the early 1990several other sensor products
been commercialized and are still in use today.
At Illinois Institute of Technology [IIT] since 1997, Dr.
Stetter has continued his interest in advanced sensor technology. He
TTI in 1999 to explore the use of a new nanotechnology enabled sensor
improvement. This has led to an additional new generation for
sensors with long lifetime, high performance, miniaturized designs, and
cost. This unique combination of sensor features, available at a cost
effective price, is sure to become another
industry standard in years to come, but for now is only available
Transducer Technology, Inc.Commercial products based on Dr. Stetter’s
more than 25 years of
sensor research and development work are in use today, and more, based
nanotechnology and MEMS, are now emerging.
Dr. Stetter is professionally active having more than 200
publications, 25 patents, and various member services to the sensor
He has been Chairman of the Electrochemical Society Sensor Division, a
of Sigma Xi since 1980, and members of the American Chemical Society
and many other organizations. He has won awards for his work, including
IR-100 Awards; the Federal Laboratory Consortium Special Award for
in Technology; Transfer, the Argonne National Laboratory Inventor’s
2002 TMAC [Technology Management Association of Chicago]
“Entrepreneur-of-the-Year” award, and two NASA New Technology Awards.
Stetter has served on the Board of Directors of four U.S. Corporations,
been a worldwide invited lecturer and speaker, and has served on the
and International Science Advisory boards. He has also served as an
several scientific peer review journals, has been a guest international
for “Sensors and Actuators”, and has been Chairman of the Electronic
Symposium and Chair of the On-site Analytical Conference. Currently, he
continues his commitment to protection of human health and the
the incorporation of cutting-edge science and nanotechnology into
sensors, analytical methods, and instruments for toxic gases and
agents that cause disease.
