Harvard researchers have invented a mask that can test the wearer for COVID:
Researchers at Harvard University’s Wyss Institute for Biologically Inspired Engineering have figured out how to integrate a freeze-dried diagnostic Covid-19 test into a face mask. The test reacts with exhaled particles and gives a diagnosis in 90 minutes or less.
The tests and a tiny blister pack of water can be mounted on any mask. After the mask has been worn for at least 30 minutes, a person punctures the blister pack to release the water needed to rehydrate and run the reactions. The test result is indicated by one or two lines, similar to a pregnancy test
The masks will be affordable and could be useful for a lot more than COVID:
The Wyss team…expects the product to cost about $5. The technology can be targeted to identify other viruses and variants as well.
Any such masks would be subject to FDA approval. Another team at University of California, San Diego is working on a sticker that could be stuck to any mask to test the wearer. Those stickers could cost mere cents.
