Wireless cylindrical piezoelectric pressure/temperature sensor for fuel tank monitoring at cryogenic environment

NASA is looking for advanced sensor technologies, especially wireless embedded sensor systems, to support rocket propulsion development. The enabling technology should provide a highly flexible instrumentation solution capable of monitoring remote or inaccessible measurement locations. This sensor system should substantially reduce operational costs and evolutionary improvements in ground, launch and flight system operational robustness. It should provide an advanced diagnostics capability to monitor test facility parameters including temperature, pressure, strain and near-field acoustics. To address this critical need, X-wave Innovations, Inc. (XII) and University of North Texas (UNT) propose to develop an innovative wireless LGS cylindrical-type pressure/temperature sensor that will bridge the gap between the urgent needs from NASA and the state-of-the-art sensing techniques. For the Phase I program, XII will prototype a wireless LGS sensor system and demonstrate the feasibility of the proposed technique for cryogenic pressure/temperature measurements and wireless data transmission. For the Phase II program, XII will focus on refining the prototype system design and development with improved hardware and software. For the Phase III program, XII will focus on optimizing the prototype performance and collaborating with our commercial partners to package the sensor technology into a commercially-available system.
