Electrochemical Carbon Dioxide Sensor for Plant Production Environments, Phase II

The aim of this proposal is to develop a low power consuming solid polymer electrolyte based, miniaturized electrochemical CO2 sensor that can continuously, accurately and rapidly monitor CO2 for monitoring and control approaches of plant-production environments, to aid in NASA's biomass (edible food) production research. The proposed sensor will introduce a much simpler, lower cost and more accurate alternative to the existing infrared CO2 measurement technology to measure CO2 and study its effects on plant growth. During Phase I, in addition to concept feasibility demonstration, the ability of the proposed sensor to detect (0 - 10) % CO2 in a wide temperature (15 ? 45)degrees C, and humidity (10 ? 99) % RH was demonstrated. In Phase II the sensor will be integrated into a complete instrument and will undergo extensive testing for accuracy, specificity, longevity and statistical comparison to existing technology. The instrument will be small, lightweight and will allow for independent operation of the sensor complete with calibration routine, adjustable applied potential settings and digital display of numeric results. The unit will be battery operated with an AC converter and battery re-charger.

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.
