Abstract
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.
