The breakthrough that means never charging your phone again19 February 2019
Today, the wireless charging systems available to the public, which involve placing a smartphone on a pad, are not close to that. Such “inductive charging” technology involves magnetic coils creating an electrical field, picked up by a sensor in a phone. However, the experience offers little more than plugging in a cable, since the charging works at a maximum distance of an inch.
That may just be about to change. Wi-Charge, an Israeli company founded in 2012, has developed a charging system that uses infrared light to beam energy from a ceiling transmitter to a device anywhere in a room.
