Scientists from the Universities of Tokyo and Michigan have developed a new system for wireless charging of portable devices. The study was published in the journal Nature Electronics.
They created a room with a conductive surface on the walls to generate magnetic fields. Compact magnetic coils were installed in the room to generate energy. With the correct location, it is transmitted to smartphones.
The development efficiency was at least 37 percent, and in large spaces — more than 50. It is claimed that the new method, unlike the previous ones, where microwave radiation was used, is safe and complies with the regulations of the U.S. Federal Communications Commission and the Institute of Electrical and Electronics Engineers.
