NASA is ready to begin testing the E-Nose COVID-19 screening device prototype developed by subcontractor Variable Inc., of Chattanooga, Tenn. NASA received $3.8 million from the Department of Health and Human Services to enhance E-Nose, which was originally developed to measure air quality inside spacecraft. The updated version is intended to facilitate screening for SARS-CoV-2 by "sniffing out" the signature volatile organic compounds (VOCs) in the breath of infected individuals.
