A team of engineers, doctors and scientists from the Massachusetts Institute of Technology has developed a new technique to address one area of the shortage of personal protective equipment, or PPE, in the US.

Amid the coronavirus pandemic, US hospitals are struggling to provide their staff with PPE, including plastic face shields. Infectious disease experts say face shields are crucial because they provide a second layer of protection and can be disinfected and reused.

Martin Culpepper, an MIT engineering professor, led a team to design a new type of shield cut with a tool called a die cutter. The shield is foldable so it can be stacked in mass quantities and shipped in boxes by the thousands. Culpepper spoke to CNET along with his cardiologist colleague, Dr. Elazer Edelman. Watch the video to see how they came up with the concept.
