TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Advanced high-temperature sensor technology and bonding methods are of great interests in designing and developing advanced future aircraft. Current state-of-the-art high temperature strain sensors are made of wires or thin film deposited by PVD on shims and then welded or glued onto strainable member, which is suffering the disadvantages such as creep, relaxation hysteresis and a limited range of operational temperatures. In this proposal, Boston Applied Technologies Incorporated (BATi) proposes to develop a novel high temperature strain gauge system through direct deposition technique. The strain gauge material features lower temperature coefficient, high structural stability and resistance to oxidation at high temperature. A temperature compensation circuit is employed in this design to minimize the effect of temperature change. Moreover, the insulating coating and protective coating are deposited by the same direct deposition technique to secure the accurate strain measurements on various hot structures, and making the whole system in a high efficient and low cost manner.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The development effort of this program will directly contribute to NASA's Fundamental Aeronautics Program (FAP). This technique will provide a viable and promising solution in developing advanced high temperature sensors in measuring strain of structural components at elevated temperatures, which will enable the design and development of advanced future aircraft.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Successful development of high temperature strain gauge has wide application in both commercial and military industries. The high temperature strain gauge can be used to monitor the leading edges of hypersonic vehicles or gas turbine blades working under high temperature (up to1000 oC), thus provide important information for system design and safety evaluation.
