Embedded high-temperature strain sensors for in situ interrogation and damage prognosis

MesoScribe Technologies proposes to develop in-situ sensing technologies to interrogate material and damage states in aerospace components operating in harsh environments e.g., gas turbine engines. Sensors will be fabricated using Direct Write (DW) technology for coupon-level testing. Phase I will focus on demonstrating durability and reliability of DW sensors under mechanical loading at high temperatures. Resistive strain gages and gage arrays will provide in-situ monitoring of damage states, with provision for environmental signal disturbances. Sensors will be designed for embedding within functional components, but evaluated on standardized specimens for fundamental performance analysis. Pratt & Whitney will act as a strategic partner, providing specifications for the operational environment, sensor fidelity and engine compatibility.
