Scientists at Disney’s Research Lab have developed a new method to wirelessly charge several electronic devices in a room by eliminating the need for electrical cords or charging cradles. By using this technology, one can charge smartphone, Laptop, tablets and other electronic gadgets.
Alanson Sample who is associate lab director and principal research scientist at Disney Research in the US said that this new innovative method will make it possible for electrical power to become as ubiquitous as WiFi.
Alanson said that we have demonstrated room-scale wireless power. As per the scientist Alanson Sample that wireless power transmission is a long-standing technological dream.
Today, most wireless power transmission travels very short distances, typically involving charging stands or pads.
The method called quasistatic cavity resonance (QSCR) involves inducing electrical currents in metallised walls, floor and ceiling of a room, which in turn generate magnetic fields that permeate the room’s interior.
The QSCR method enables power to be transmitted efficiently to receiving coils that operate at the same resonant frequency as the magnetic fields.
The induced currents in the structure are channelled through discrete capacitors, which isolate potentially harmful electrical fields.
Matthew J Chabalko from Disney Research said that our simulations show we can transmit 1.9 kilowatts of power while meeting federal safety guidelines.
Matthew said that this is equivalent to simultaneously charging 320 smartphones.
The researchers constructed a 16×16-foot room with aluminium walls, ceiling and floor bolted to an aluminium frame. A copper pole was placed in the centre of the room; a small gap was created in the pole, into which discrete capacitors were inserted.
Matthew said that it is those capacitors that set the electromagnetic frequency of the structure and confine the electric fields.
