Sensor Systems and Microsystems - From Fabrication to Application

In This Section

Synopsis:


The introduction of sensor technology, including smart microsensor systems, into Aerospace applications is rapidly expanding to allow improved system monitoring and provide gains in efficiency, performance, critical data, and safety. This short course is taught by three experts in sensor technology and its application to provide not only an overview of microsensor fabrication and development, but also a practical discussion of the implementation of sensor systems in space applications. The first half day of the course will concentrate on micro/nano-fabrication techniques and processes taught by Prof. Peter Hesketh of Georgia Institute of Technology. The second half day of the course will discuss case studies in sensor development taught by Dr. Gary Hunter of NASA Glenn Research Center. The last half day of the course will discuss sensor system implementation ranging from Payloads such as Mars Pathfinder to Launch Vehicle Sensor Implementation such as The Ares I Launch Vehicle; taught by Mr. Larry Oberle of NASA Glenn Research Center.

Key Topics:


• Advanced Throughput Capabilities: Assessment of pros and cons of on-board Micro/Nanofabrication techniques including lithography, oxidation/ diffusion processes, etching processes, and thin film deposition
• Sensor packaging and wafer bonding technique
• Case studies in sensor development, especially chemical sensor development, including a range of lessons learned and application examples
• Basic procedures and steps associated with flight qualification and deployment of sensors and sensor systems
• Examples of sensor system characterization and implementation on the Space Shuttle and International Space Station with lessons learned
• Discussion of future directions in sensor technology including smart sensors systems, nanotechnology, and applications in harsh environments

Who Should Attend:


The course is designed to appeal to a wide market audience. Every vehicle subsystem can be positively impacted through the proper design and implementation of sensor technology. This course provides a significantly improved understanding of emerging sensor technology through lessons in microsensor fabrication, sensor development, and aerospace sensor implementation.
