High Temperature Sensing Parameters

Syntonics will establish the feasibility of high-temperature Surface Acoustic Wave (SAW) devices by demonstrating viable approaches to the materials science and SAW design/fabrication issues raised by extreme temperatures. SAW devices fabricated from appropriate crystal structures at certain cut angles are capable of operating at temperatures above 750 C and provide highly accurate and robust capability. Further, they are versatile and can be employed for many sensing applications including temperature, pressure, gas, strain, and heat flux and flow. Syntonics has already demonstrated the feasibility of wirelessly telemetering strain data from SAW devices capable of operating at 300 C while installed in a jet engine.
