High Temperature Sensing Parameters Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-037 Topic Title: High Temperature Sensing Parameters Proposal No.: N081-037-0161 Firm: Syntonics LLC 9160 Red Branch Road Columbia, Maryland 21045-2002 Contact: Steven Gemeny Phone: (410) 884-0500 Web Site: www.SyntonicsCorp.com Abstract: 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. Benefits: The first application for this technology will likely be jet engine testing at Government and industry laboratories. The ability to wirelessly telemeter data from hot moving parts will make these sensors especially attractive for rotating engine machinery, where wired sensors are impractical or impossible and temperature can be extreme. However, high temperature sensors are used in hundreds of other specialized industrial control applications. Wherever a wireless sensor can compete favorably with a wired sensor, this technology has an opportunity in the marketplace. Return
