Wireless power supply like wi-fi New method of researchers

Wireless power supply like wi-fi? Researchers’ new method

Soon cables tangled under our feet may disappear. That’s thanks to a new technology developed by engineers at Disney Research that allows electronic devices to be powered wirelessly.

The new method is called quasistatic cavity resonance (QSCR), and it allows the use of electronic devices in such a simple way toób, such as the use of wi-fi technology. Engineers from Disney Research demonstrated a wireless-capable Pokój. In any of its places one can, for example. charge their phone or power household appliances.

Pokój shown by the researchers was specifically built. Its walls conduct the current. A copper pipe was placed in the center of the room. QSCR technology generates standing magnetic waves and, thanks to special receivers, devices can benefit from wireless power supply.

An alternating electric current is generated in the walls, floor, ceiling and in a pipe placed in the middle of the room, który induces a magnetic field. The copper tube contains capacitors, thanks to which theórym can determine the frequency of the magnetic field.

The scientists leading the teamóat Alanson Sample argued that a small revolution could occur with the technology they developed. – Our technology will make wireless power as common as wi-fi. QSCR will make possible new applications for mobile devices, such as roboticów, whoóre will not need batteries and chargers – expert said

– Currently, our system works in a room the size of a room, but it can be successfully adapted to suit the size of theów. In compliance with safety regulations, we are able to transmit in this wayób power of 1.9 kilowatts. This is enough to charge 320 smartphones at onceów – also explained Matthew Chabalko, who works on the wireless power supply.

Wireless power is now popular in inductive toothbrush chargersóin or in the panels that charge smartphones. The authors of the new technology argue that converting existing rooms to wireless power capability will be very simple.
The results of the researchers’ work were published in „PLOS ONE”.
