High Temperature, Optical Sapphire Pressure Sensors for Hypersonic Vehicles

The objectives of this project are to: (1) design a sapphire optical lever microphone via multiphysics analytical modeling; (2) develop thermocompression fabrication methods for the formation of devices with moving parts out of sapphire and platinum; (3) develop techniques for ultrafast laser micromachining of sapphire for sensor and packaging fabrication; (4) fabrication and packaging of pressure sensors optimized for low-noise and high-sensitivity while possessing minimal drift associated with changes in relative humidity, temperature, etc.; (5) characterize sensors in a simulated, high temperature, pressurized laboratory environment; and (6) implement a hypersonic flow facility (such as Arnold Engineering Development Center, etc.) and/or a gas turbine (such as the Capstone C60 microturbine at the University of Florida, etc.).
