The engineers whose Badger Shield design drew worldwide demand are back with a new pandemic-inspired design, one they say will dramatically increase the effectiveness of standard face masks.
The innovation came after a study by two University of Wisconsin-Madison mechanical engineering professors revealed that various existing masks and face shields allow tiny particles to escape, both through the material and at the edges. If the wearer is infected with the novel coronavirus, that means the virus could travel from the wearer’s mouth or nose and infect those around them.
