A group of Chinese scientists have developed a face mask that can detect viral exposure from a 10-minute conversation with an infected person.

According to the study published this week in the journal, Matter, respiratory pathogens that cause COVID-19 and influenza spread through small droplets and aerosols released by infected people when they talk, cough, and sneeze.

The wearable bioelectronics mask designed by the researchers from Tongjin University can detect common respiratory viruses, including influenza and the coronavirus, in the air in droplets or aerosols, and then alert the wearers via their mobile devices.

The highly sensitive face mask is capable of measuring trace-level liquid samples of 0.3 microliters and gaseous samples at an ultra-low concentration of 0.1 femtograms per milliliter.
