Russian engineers have developed an innovative wireless smartphone charging system. The new technology, developed at St. Petersburg ITMO University, allows devices to be charged simply by placing them in a special room.
The method of wireless energy transfer is not only as efficient as traditional wired chargers, but also completely safe for humans.
The prototype charging room has dimensions of 4×4 meters with a height of 2.5 meters. The system operates at a frequency of 1 MHz, and a special phone case acts as an energy receiver. It is important to note that the technology is capable of simultaneously charging an unlimited number of devices.
The invention is universal — the system can be easily adapted to various sizes and shapes of rooms. The team's immediate plans include improving the technology to charge devices in any position, not just horizontally.
The engineers want to pay special attention to improving the polarization of the magnetic field, which will make the charging process even more efficient.
