A team of Harvard and MIT researchers have come up with an invention that combines the two strategies for stopping the spread of respiratory illness. They pioneered a wearable biosensor that can do the work of an entire laboratory — and it's small enough to clip onto a face mask.
Wearers breathe into their masks for 15 to 30 minutes, press a button on the sensor, and within 90 more minutes, their COVID test results show up on a readout strip similar to a pregnancy test.
The same technology could be used to identify another pathogen, like influenza. The detection is so precise — down to the individual building blocks of DNA — that it could even differentiate between COVID variants.
The researchers said the testing sensitivity is comparable to the gold-standard RT-PCR tests, and it turns out results relatively quickly. The device is also inexpensive — without accounting for packaging, the prototype cost five dollars to make, and the final product could be made for even less.

I can't wait to see this potential revolutionary product in market. If it's good enough for covid, other versions can be developed for other viruses.
