Over fifty years ago, the Nobel Prize-winning physicist Richard Feynman claimed that a revolution was underway where information, computers, and machines would be shrunk to incredibly small dimensions. History has proven him mostly right: Moore’s law have given us microelectronics, the internet, and artificial intelligence. But the third leg of Feynman’s dream, the miniaturization of machines, is only just getting underway. Can we create functional, intelligent machines too small to be resolved by the naked eye? The size of, say, a single-celled Paramecium? And if so, how? In this talk, I’ll talk about a Cornell effort to combine microelectronics, optics, paper arts, and ultrathin materials to create a new generation of light-powered smart, active microscopic robots.
