Artificial Robot Skin May Offer Virus Protection

A new chemical-sensing robot skin is being developed at Caltech, providing robots a newfound ability to sense infectious bacteria, viruses, and more.

"Modern robots are playing a more and more important role in security, farming, and manufacturing," says Wei Gao , Caltech's assistant professor of medical engineering. "Can we give these robots a sense of touch and a sense of temperature? Can we also make them sense chemicals like explosives and nerve agents or biohazards like infectious bacteria and viruses? We're working on this."
