RESEARCHERS TURN ROOM INTO WIRELESS CHARGER-Researchers turn room into wireless charger
「研究者たちが部屋を無線充電器に変える」
June 26, 2019-

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 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.

“We want to create a world where you can charge your device without even thinking about it.”

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