Face mask that detects COVID-19 in 90 minutes made: US researchers

Researchers from MIT and Harvard University have developed a face mask embedded with tiny, disposable sensors that can detect COVID-19 infection. The masks require wearers to breathe into them for 15-30 minutes and then press a button on the sensor. This releases a small amount of water and provides COVID-19 test results within 90 minutes on a readout strip.
