A dash of graphene can transform Silly Putty into a pressure sensor able to monitor a human pulse. Nicknamed G-putty, the new material could be developed into a device that continuously monitors blood pressure. It also demonstrates a form of self-repair that may produce even smarter graphene composites. Not only are we evolving, but we are evolving the materials around us.
