A team of Yale scientists and engineers has developed a wearable COVID-19 detector that samples the air for the virus and can alert users to an exposure. The device, named the Fresh Air Clip, was designed to detect the virus at levels well below what is considered an infectious dose.
In a test, samplers were embedded in wearable clips and worn by 62 people across Connecticut. The samplers were then examined using state-of-the-art PCR technology for signs of exposure to the virus, which can be transmitted in aerosols or droplets.
