Thanks to the new technology, the process of charging gadgets will be significantly simplified
A group of Finnish scientists from the University of Aalto has made significant progress in the transmission of electricity in a contactless way. They were able to transfer electricity from one 7.2 cm coil to another at a distance of 18 cm. The transmission efficiency was 80%.
At first glance, it may seem that 18 cm is not so much. In fact, we are talking about a real breakthrough. Wireless chargers on the market involve physical contact of the gadget being charged with an induction pad. According to experts, this is why the process of introducing wireless charging is too slow.
The main problem with wireless chargers is that as the distance between the inductive area and the gadget being charged increases, the efficiency of wireless charging begins to decline. Finnish scientists have developed a dynamic theory of contactless charging that makes it possible to increase the efficiency of power transmission over long distances.
According to researchers from Aalto, the day is not far off when people will no longer have to worry about charging their smartphones. They will receive electricity through the air while users go about their business.
