Aerospace applications require a variety of sensing technologies to monitor conditions related to both space exploration and aeronautic aircraft operations.  One topic of this talk is the effort to produce microsensorplatforms and smart sensor systems that can be tailored to measure multiple chemical species.  Applications include leak detection, engine emissions monitoring, fire detection, human health monitoring, and environmental monitoring.  This technology development ranges from development of base sensor platforms to the evaluation of more mature systems in relevant environments.  The introduction of nanomaterialsinto microsensorplatforms has the potential to significantly enable improved sensor performance, but fabrication control of those nanostructures is necessary to achieve maximum benefits. 
This talk also discusses harsh environment, high temperature sensor system technology development. Specific areas of work include silicon carbide (SiC) based electronic devices, sensors and wireless; thin film thermocouples, strain gages, and heat flux sensors; chemical species emissions sensors; MicroElectroMechanicalSystems (MEMS), as well as integrated and multifunctional sensor systems.  Each sensor type has its own technical challenges related to integration and reliability in a given application. 
Examples will be given of harsh environment sensor systems, microsensorplatform technology, smart sensor systems, application testing, and efforts to integrate and control nanostructures into sensor structures.  Although microsensorsystems can have a significant impact on aerospace applications, extensive application testing is necessary for their long-term implementation.  It is concluded that the core technologies for smart sensor systems being developed for a range of operational conditions can enable the long-term vision of intelligent vehicle systems.


Dr. Gary W. Hunteris Lead for Intelligent System Hardwareand the Technical Lead for the Chemical Species Gas Sensors Teamin the Sensors and Electronics Branchat NASA Glenn Research Center.  He has been involved with the design, fabrication, and testing of sensors for nearly 20 years for a range of applications.  This work has included the use of micro and nanotechnology 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-43, International Space Station, Jet Engine Test Stands, Ford Motor Company Assembly line, and on the Ford U Car.  He has been corecipientof two R&D 100 Awardsfor one of the most significant inventions/products of the year, two NASA Turning Goals Into Reality Awardsand one Nano50 Award.  He has been involved in a range of activities involving the development, demonstration and application of sensor technology.  He is former Chair of the Sensors Division of the Electrochemical Society.
