Researchers from Japan and the United States have developed a wireless charging technology that could safely charge entire rooms with up to 50 watts of power.
The first news we had of a wireless charger was, of course, related to the world of smartphones. Fixed plates that could load the mobile just by resting on them, eliminating cables.
Although this was not enough, it meant that charging through wireless technology was feasible, so sooner or later something would come to revolutionize the world of charging as we know it.
And that moment seems to have come. In a published study In Nature Electronics, researchers from the University of Michigan and the University of Tokyo have developed a system to supply electricity safely through the air.
The technology, the publication details, can supply 50 watts of power using magnetic fields currently.
To prove your theory, the researchers created a 3-square-meter test room with aluminum walls, in which they wirelessly powered lamps, fans and mobile phones that could draw power from anywhere in the room, regardless of the location of people and furniture.
According to those responsible, the system represents a significant improvement over previous attempts at wireless charging systems, which used potentially harmful microwave radiation or required the devices to be placed in specific charging locations.
Instead, it uses a conductive surface on the walls of the room and a conductive pole to generate magnetic fields.
Mannequin testing (not tested on humans yet) showed that the system could deliver at least 50 watts of power to anywhere in the room without exceeding the Federal Communications Commission guidelines for exposure to electromagnetic energy.
Yes indeed, Researchers believe that higher power levels can be delivered with further refinement of the system, which would allow loading entire offices.
Lastly, officials say that by charging phones and laptops, the technology could power human-implanted medical devices and open up new possibilities for mobile robotics in homes and factories. And meanwhile Xiaomi insists on breaking records.
