One day, however, the entire surface of a phone might be made of nano cameras. Each one would be no bigger than a grain of salt. Yet they could take photos comparable to traditional cameras.

That might sound like sci-fi technology you'd see in a movie, but researchers from Princeton have made such a camera design possible. And while it might take a while for companies like Apple, Samsung, and Google to even consider such micro-cameras, the salt grain-sized cameras could be incredibly useful in fields such as medicine and robotics.
