Process-Hardened, Multi-Analyte Sensor for Characterizing Rocket Plum Constituents Under Test Environment, Phase II

The objective of the Phase II STTR project is to develop a prototype multi-analyte sensor system to detect gaseous analytes present in the test stands during propulsion test activities. Data on the concentrations of propellant-derived species are important to assure proper integration of safety protocols with testing activities to comply with environmental regulations. InnoSense LLC (ISL) has utilized its Chemical Fingerprint(TM) sensor array fabrication technology in Phase I to establish the feasibility of the multi-analyte approach. In particular, we have detected carbon dioxide, isopropanol, carbon monoxide, kerosene and ethylene as potential target analytes in the test stands. We have employed pin printing-based fabrication strategies, which would allow us to customize the sensor suite specific to engine types using different propellants. Concerning the placement of the sensors at the test stands, NASA users will use their discretion in deciding the location based on CFD (Computational Fluid Dynamics) reports. The sensors developed under this project can be used to validate these CFD models. ISL has received endorsement letters on the technology from two NASA prime contractors. ISL has also secured Phase III funding commitment from two commercialization partners. For assuring success of this project, ISL has assembled a technical team with a cumulative 90 person-years of experience in developing commercially viable sensor systems.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
