Charging Your Devices Could Be as Simple as Connecting to WiFi in 2018

• Disney researchers have developed innovative technology that will allow people to charge their devices in a truly wireless fashion

• If this technology could be commercially adopted, it could revolutionize the way that we use and create everything from smartphones to AI robots

Today, we still rely on wired charging for our phones, tablets, and laptops. Wi-Charge is working on a long-range wireless charging system that will send power to your device wherever it is in the room, no cords or careful placement on a charging mat needed.

Excitingly. Disney Research just demonstrated a new method of charging called quasistatic cavity resonance (QSCR) that allows power to be wirelessly transmitted throughout a room, which means you can easily go about using your devices while you charge your battery.

QSCR works similar to how WiFi hotspots provide internet connectivity wirelessly. By inducing electrical currents in the metalized interior, they were able to generate uniformed magnetic fields that then transmitted to receiving coils which follow the same resonant frequency. Devices that operate in the same megahertz frequency could receive power at any point in the room, while magnetic waves that don’t have the same frequency are unaffected.

Research simulations show that this method can effectively transmit 1.9 kilowatts of power, which could fully charge 320 smartphones.


Scientists have been working for years to create stable and reliable wireless power transmission. But, the closest we have come to achieving it today, prior to this breakthrough, was through using charging pads and cradles, which don’t offer much distance. This new development is the first step towards truly wireless charging tech.

To make this technology commercially available, there won’t be a need to construct entirely new, metal rooms. The researchers believe that as they refine the technology, it will be possible reduce the required metal for interiors. They also think that people will be able to simply add modular panels, use conductive paint, or install copper poles in existing structures to get the same results.

This innovative method could be a technological game changer because it essentially makes electrical power as accessible as WiFi, lending itself to new applications—from portable electronics to robotics & can also be extended to onboard electronics.
