Japanese experts made the whole room a wireless charger
TOKYO: Believe it or not, the end of smartphone scrutiny has become one of the biggest headaches and fears of our time. The solution is now presented by Japanese experts in the form of a revolutionary room that can charge any electrical device within the range wirelessly.
Although wireless charging phones, smartwatches and earphones have become commonplace, Takoya Sasatani, a professor at the University of Tokyo, has developed a new type of technology called ‘Multi-Mode Quasi-Static Cavity Resonance’. In it, they have installed capacitor coils in places in a room three meters wide, two meters long and three meters high. This creates an unseen magnetic field throughout the room. However, the electric field remains trapped in the capacitor. Then he placed a circle of copper in the middle of the room, from which the magnetic field emanated clockwise and counterclockwise. This leaves no space in the room and the charge reaches everywhere. Now everything from phones to tablets is kept there, getting electricity and charging.
But wireless signals reach 2% of the room area or corners and get about 50 watts of electricity. On the other hand, the magnetic field in a room is not strong enough to affect a human being and thus the whole electric room is completely harmless to human beings. Although the charging device is placed at the right angle, it charges fully, but some of the charging continues even when it is turned away.
It should be noted that in 2017, Disney’s research department had also built a charging room in which the main copper coil was later removed. However, despite this significant success, no progress has been reported from Disney so far.
Analysts say the University of Tokyo’s charging room is more practical and better. Japanese experts insist that the same thing can be done with a wireless charging cupboard and box if you don’t want to make room. In this regard, Xiaomi has created an air charge box in which every device placed inside can be charged wirelessly. Xiaomi has not yet announced its intention to launch it.
