FreshAirClip – Wearable detects personal exposure to SARS-CoV-2

What is this new device?

“The Fresh Air Clip is a wearable device that can be used to assess exposure to SARS-CoV-2 in the air,” said the clip’s creator Krystal Godri Pollitt, Ph.D. an assistant professor of epidemiology (Environmental Health Sciences) at the Yale School of Public Health and also an assistant professor of chemical and environmental engineering at Yale.

Briefly, how does it work?

Exhaled respiratory droplets and aerosols can carry infectious viruses and are an important mode of transmission for COVID-19. Recent studies have been successful in detecting airborne SARS-CoV-2 RNA in indoor settings using active sampling methods. Integration of passive samplers into wearable designs can be used to better understand personal exposure to the respiratory virus.

“With this clip we can detect low levels of virus that are well below the estimated SARS-CoV-2 infectious dose,” Godri Pollitt said. “The Fresh Air clip serves to identify exposure events early, alerting people to get tested or quarantine. The clip is intended to help prevent viral spread, which can occur when people do not have this kind of early detection of exposure.”
