"Engineers at MIT and Harvard University have designed a novel face mask that can diagnose the wearer with Covid-19 within about 90 minutes. The masks are embedded with tiny, disposable sensors that can be fitted into other face masks and could also be adapted to detect other viruses."
It's like a wearable Microtox BT....... and takes a lot longer (90mins Vs 4secs) to detect..... :()
All the best (Still a great device no doubt...... :)
