According to Sci-News, a team of researchers at the University of Washington have developed a prototype mobile phone optimized for the transmission and reception of speech and that is powered entirely by ambient light and radio signals, allowing for continuous operation.

“The cellphone is the device we depend on most today. So if there were one device you’d want to be able to use without batteries, it is the cellphone,” said senior author Professor Joshua Smith, from the Allen School and the Department of Electrical Engineering at the University of Washington.

“The proof of concept we’ve developed is exciting today, and we think it could impact everyday devices in the future.”
