“Hello, hello. I am calling from a battery-free phone.” Vamsi Talla’s words in a cluttered lab at the University of Washington in Seattle are barely audible through pops and static. But the fact they can be heard at all, on a nearby Android smartphone, is revolutionary, because Talla’s own cell phone has no battery at all. […]
