Nickel-based sensor utility is limited when exposed to high temperatures for long periods, due to oxidation effects which affect durability and repeatability.  This work addresses these shortcomings using precious metal-based devices, including thermocouples and strain gages, which potentially offer higher longevity and more consistent response over sensor lifetime.  Devices are deposited by Mesoplasma Direct Write, a high-precision derivative of thermal spray, capable of embedding multilayer thick-film devices onto surfaces and within coatings.  In-situ temperature and strain measurement capability in engines and other harsh environments supports HM by reducing uncertainty, and consequently extending service intervals and increasing asset availability.
