The new mask uses a biosensor to detect respiratory viruses in air droplets, letting the wearer know if COVID-19 is present in the air.


This article by Jessica Black, writing for ABC-Australia, makes the following points:
  • An embedded wireless device alerts the wearer's phone if pathogens are identified.
  • The sensor in the mask detects as little as 0.3 micro-litres of liquid containing the virus—hundreds of times less than the volume of liquid produced in just one sneeze.
  • The study's co-author, Dr Yin Fang, believes the bio-electronic mask could be adapted to detect emerging viruses and prevent future outbreaks.
