Researchers at the University of Washington Created a new mobile phone that never needs to be charged and can draw its power from air rather than relying on lithium battery cells.
The mobile phone is capable of converting radio waves at a specific frequency into power. It may not be copious amounts of power but it is enough to enable signals. One of the other features of the phone is that analog speech isn’t converted to a digital signal.
The mobile phone has been developed over the past year by Vamsi Talla, a research associate at the lab of Joshua Smith, who researches computer science and electrical engineering at UW who explains to Wired in an interview that “Converting analog human speech to digital signals consumes a lot of power,” – “if you can communicate using analog technology, you’re actually more power efficient.”
