This entire living room is a wireless charger

2021-09-03 00:00:00

We've become accustomed to wireless chargers that harness a phenomenon called electromagnetic induction to power up nearby mobile devices. The range is very low though, usually requiring the device to be placed right on top of the charging coil. Now though, University of Tokyo researchers and their colleagues have built a model living room that wirelessly powers a lamp, fan, smartphone, and other electric devices.

The room's walls are conductive aluminum panels that work like a scaled-up version of a wireless smartphone charger, creating a three dimensional magnetic field inside. And no, it won't electrocute you.
