Technology Development for High-Temperature Sensors
Abstract
The University of Florida (UF) proposes the development of basic science and technology to enable the realization of high-temperature, MHz-bandwidth dynamic pressure sensors for hypersonic flow measurement applications. The ultimate goal of this research program is to support the development of scientific-grade dynamic pressure sensors using microelectromechanical systems (MEMS) high-temperature gallium nitride (GaN) piezoelectric sensing technology to operate in environments exceeding 500 degreesC. In addition, the technology development is expected to enable transducers possessing bandwidths exceeding 1 MHz that enable NIST-traceable calibration throughout the measurement bandwidth. The ultimate goal of a future high temperature sensors program is the monolithic integration of the sensor and AlGaN-GaN-based signal processing and conditioning electronics. The resulting transducer technology will provide a crucial high-temperature capability beyond that of existing sensors, eventually enabling quantifiable dynamic pressure measurements in high-speed flows that are a critical capability for reduced-scale testing of next-generation hypersonic vehicle and weapons designs in support of the Air Force Speed and Reach of Disruption and Lethality Strategic Capability.1 The proposed technology is particularly well suited for use in a variety of Department of Defense (DoD), National Aeronautics and Space Administration (NASA), and other government- and university-owned high-speed ground-test facilities and flight-test articles by providing a robust, reliable, small form-factor sensor.
