Method development of self-correction for real time CO2 monitoring using an ultra-low power and wearable sensor, Year 2

Completed TRL 2 (started at 1, targeting 2)

Description

The approach is to integrate ARC CO2 nanosensor chip with JSC low power RFID platform for real-time CO2 concentration monitoring. This includes developing a method for real-time CO2 concentration monitoring and ultra-low power consumption in μW for long life (years without battery change). This work will develop a method of self-correction using onboard temperature and humidity sensors to feedback information to the electronics and obtain the absolute sensor response value for real-time CO2 concentration monitoring. This will be a breakthrough in our sensor technology for space and terrestrial applications.

Benefits

NASA crew members need a class of deployable air quality sensor that can monitor the CO2 concentration in real-time for ISS and space suits and operate for months-to-years without needing to be recharged or battery change. This work develops a method of self-correction to obtain reliable sensor response using the low power and small footprint nanosensors and RFID to provide long life, one-button operation, mobile and always-on environmental sensing capability. ARC developed a low power and small footprint CO2 sensor and JSC developed an RFID platform that consume very little power. Two teams work closely to integrate their advanced technology to provide an extreme long life wearable device for environmental monitoring.

How to get involved

This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

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.
