MIT researchers are testing prototypes for heated face masks, per a university release
Researchers at the Massachusetts Institute of Technology (MIT) reportedly submitted a patent for a mask with heated copper mesh. The contraption is said to slow particles down and inactivate viruses in mere seconds by the mesh and temperatures reaching 90°C, or 194°F.
“While facial coverings over the nose and mouth reduce the spread of the virus SARS-CoV-2 by filtration, masks capable of viral inactivation by heating could provide a complementary method to limit viral transmission,” study authors wrote.
Findings were posted ahead of peer review on the arXiv depository.
