An Integrated Approach to Sensor Materials Synthesis, Design and Fabrication for Extreme Temperature Applications

An approach is proposed to identify, characterize and integrate high temperature materials into harsh environment diagnostic systems. Program partner URI will sputter candidate conductive oxides with continuously varying levels of doping. Test specimens will be fabricated and systematically assessed using combinatorial synthesis to determine which exhibit the most favorable characteristics e.g., high temperature stability, consistency, sensitivity, for sensor use. MesoScribe Technologies will apply its Mesoplasma Direct Write process, a high-precision derivative of thermal spray technology, to deposit the selected materials in precise sensor architectures. URI's experience in material characterization and ceramic oxide strain gages will be combined with MesoScribe's expertise in sensor design and fabrication to achieve application-specific measurement capability in high temperature (1600C) regime of gas turbines and hypersonic structures.
