Charging smartphones "through the air": is the world ready for this technology?

A group of scientists from the USA and Japan have built a room where all the equipment works without wires. There is not a single socket in the room, because the electronics receive energy “through the air” from special power sources. Scientists from different parts of our planet have previously tried to create such technology, but they constantly encountered various problems. Sometimes the transmitted energy was very weak and smartphones took too long to charge. And in other cases, this problem was compounded by the fact that blind spots appeared in the room, where the equipment could not receive a charge. The creators of the new technology assure that all these problems have been completely eliminated in the room they built - you might think that it has no flaws at all. The engineers briefly explained the principle of operation of the applied method of charging devices and showed what the room they created looks like.



Details about the scientists’ next achievement were published on egypt number data the University of Michigan website. The room measuring approximately 3 by 3 meters is completely covered with aluminum. This material was egypt number data necessary to ensure high electrical conductivity — in this parameter it ranks fourth after silver, copper and gold. To make the room look beautiful, the aluminum coating was hidden behind thin partitions. Thanks to special poles that generate a magnetic field, there is always a magnetic field inside the room with a radiation of about 50 watts. This is enough to allow a lamp, fan and other equipment to work in the room without any sockets. According to the engineers, neither standing furniture nor people entering the room interfere with charging the devices.

How does over-the-air charging work?
In short, the principle of operation of charging "through the air" is that there are elements in the room that create a magnetic field - they are located outside the walls and are not visible. To capture the energy created inside the lamp, fan and other equipment, there is a special coil. Previously, the problem of such a system was the low charging power, but the authors of the scientific work assure that they somehow managed to fix everything. They also eliminated the blind zones that arose due to the fact that the magnetic fields around each generator had an oval shape - voids appeared in the corners of a square room. This problem was solved by a more thoughtful arrangement of the generators.
