Chemical Micro/Nano Sensors for Aerospace Applications
Gary W. Hunter, Ph.D.
NASA Glenn Research Center
(VIDEO CONFERENCED FROM NASA GLENN RESEARCH CENTER IN CLEVELAND OHIO)
Abstract:
The aerospace industry requires the development of a range of chemical sensor
technologies for such applications as leak detection, emission monitoring, fuel
leak detection, environmental monitoring, and fire detection. A range of chemical
sensors are being developed based on:
- Micromachining and microfabrication technology to fabricate microsensors with minimal
size, weight, and power consumption.
- The use of nanomaterials and structures to
develop sensors with improved stability combined with higher sensitivity.
- The development
of high temperature semiconductors, especially silicon carbide, to widen the operating
temperature range of Schottky diode gas sensors.
However, individual sensors are
limited in the amount of information that they can provide in environments that
contain multiple chemical species. Thus, sensor arrays are being developed to
address detection needs in such multi-species environments. The sensors that
compose these arrays have differing detection mechanisms to produce marked
differences in their responses and improve the ability to determine the chemical
constituents of an environment.
This presentation discusses sensor and sensor
array development for a range of aerospace applications, demonstration of these
arrays, and their relative stage of development.
Bio: Dr. Gary W. Hunter
Dr. Hunter is the Technical Lead for the Chemical Species Gas Sensors Team and
Lead for Intelligent System Hardware in the Sensors and Electronics Branch at NASA
Glenn Research Center. He received his BS in Physics and Philosophy at Michigan
State University in 1980 and his Ph.D. in Physics in 1986. He worked for three years
at Engelhard Corp. before joining NASA in 1990. Since his arrival at NASA Glenn,
he has been involved with the design, fabrication, and testing of sensors esp.
chemical species gas sensors. This work has included the use of both micro and
nano technology as well as the integration of sensor technology into smart systems.
Technology he has led the development of has been chosen, demonstrated, or applied
in applications such as the Space Shuttle, NASA Helios Vehicle, X-33, X-43,
International Space Station, Jet Engine Test Stands, the Ford Motor Company
Assembly line, and on the Ford U Car. Dr. Hunter has taught short courses on
chemical sensing technology, co-authored two book chapters, and is involved
in a range of sensor related technology development.
Dr. Hunter is past Chair of the Sensors Division of the Electrochemical Society
and a member of the Controls, Diagnostics, and Instrumentation Committee for the
International Gas Turbine Institute. He has been awarded the R&D 100 Award (2005),
NASA Turning Goals into Reality Award Associate Administrators Choice Award (2005),
NASA Group Achievement Award (2006, 2004, 2003, 1998), Silver Snoopy (2000),
NASA Exceptional Achievement Medal (1998), and Space Flight Awareness Award
(1997), R&D 100 Award (1995).
