Researchers from Harvard University and MIT have developed a new face mask that can detect whether the wearer has had a COVID-19 infection within about 90 minutes. This face mask has been designed by engineers from the Weiss Institute for Biologically Inspired Engineering at Harvard University and the Massachusetts Institute of Technology (MIT). These engineers have designed a face mask that can diagnose Covid-19 infection in the wearer of the mask within about 90 minutes. These masks are embedded with small, disposable sensors that can also be incorporated into clothing or adapted to detect other viruses. A wide range of
