Researchers Turn Room Into Wireless Charger



Researchers turn room into wireless charger

University researchers are working on technology that turns an entire room into a wireless battery charger for smartphones and other devices.

A team led by Professor Yoshihiro Kawahara of the University of Tokyo ran successful tests of the technology in a specially constructed room.



The walls and floor were embedded with boards that generate a magnetic field throughout the room.

The test showed a smartphone receiving power wirelessly and the battery started charging. A light in the room also came on without being connected to an outlet.

The system removes the need to place phones and other devices next to a wireless charging device.

The researchers say no groups have yet to commercialize room-wide wireless charging technology.

The group says it is following international safety guidelines on use of magnetic fields. Its next step is to improve charging efficiency and reduce costs.
