Wireless Networked Cryogenic and Minimum Pressure Sensors

During the NASA program, we will transition the semiconductor nanomembrane self-calibrating cryogenic and minimum pressure sensors from their current concept and prototype TRL 4-5 demonstration stage, to near-term instrumentation products of use to NASArsquo;s propulsion system facilities, other NASA instrumentation programs, academic researchers and industrial technologists. NanoSonic will again work cooperatively with our Virginia Tech university partner to improve our current mechanical and electrical models of semiconductor NM-based self-calibrating sensor performance that will allow quantitative optimization of material properties and suggest optimal methods for sensor attachment and use for 1) cryogenic liquid pressure and 2) purge-box minimum gas pressure measurement applications. NanoSonic and Virginia Tech will go beyond Phase I analysis to perform a complete study of sensor cross-sensitivities and noise sources to allow optimization of signal-to-noise ratio and practical sensor sensitivity. We will provide NASA with sensor hardware and software as Phase II deliverables, and be available to provide technical support, should sensor testing on-site at NASA be possible.
