Engineers at Massachusetts Institute of Technology (MIT) and Harvard University have designed a novel face mask that can diagnose the wearer with Covid-19 within about 90 minutes, Report informs referring to the MIT website.
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.
The face mask sensors are designed so that they can be activated by the wearer when they’re ready to perform the test, and the results are only displayed on the inside of the mask for user privacy.
The mask also includes a small reservoir of water that is released at the push of a button when the wearer is ready to perform the test. This hydrates the freeze-dried components of the SARS-CoV-2 sensor, which analyzes accumulated breath droplets on the inside of the mask and produces a result within 90 minutes.
The prototypes developed in this study have sensors on the inside of the mask to detect a user’s status, as well as sensors placed on the outside of garments to detect exposure from the environment. The researchers can also swap in sensors for other pathogens, including influenza, Ebola, and Zika, or sensors they have developed to detect organophosphate nerve agents.
