This shield would protect a wearer during a coronavirus outbreak by using UV light to sterilise itself. Designed by Chinese architect Sun Dayong, this mobile safety device is for "people who are exposed to the dangerous situation during the coronavirus emergency", Sun Dayong told Dezeen. How does it work? The shield would be made from carbon fibre supports that would be worn like a backpack. A PVC film would stretch between these supports, like the membrane of a bat's wing. Wires embedded in the plastic would heat up to a temperature high enough to kill any pathogens on them, creating a sterile environment inside for the wearer. "The coronavirus will be killed by temperatures of 56 degrees Celscius. The PVC film cover is like our car windshields – there are heater wire in between the glass for heat the ice and snow in the winter," Sun has told Dezeen.
