Disney Research’s tech and science division has unveiled a prototype room that can charge electronic devices wirelessly. The system uses quasi-static cavity resonance to generate magnetic fields inside a specially engineered enclosure, allowing power to be delivered to mobile devices anywhere within that space.
“This new method could make electrical power as ubiquitous as Wi‑Fi,” said Alanson Sample, principal research scientist at Disney Research. “Removing the need for battery swaps and charging cables could enable new applications for robots and other small mobile devices.”
Unlike recent chargers that require users to set a phone on a mat, Disney’s approach enables devices to receive power while simply carried in a pocket when the user is inside the tailored room. The system is designed to transfer energy over short distances throughout the interior without direct contact.
To achieve reliable power delivery, the room must be constructed from materials and components that support the required electromagnetic behavior. The prototype relies on a largely aluminum enclosure, a central copper post, and carefully placed capacitors to separate and control the magnetic and electric fields within the cavity.
Disney Research is refining the technology with an eye toward practical deployment. If successful, the same concept could be adapted for public or commercial environments such as theme park attractions, airport lounges, waiting areas, or other indoor locations where shared, seamless wireless charging would be useful.
Key advantages of this approach include hands-free charging, the ability to power multiple devices simultaneously, and the potential to enable small autonomous systems to operate longer without manual battery maintenance. Researchers continue to work on efficiency, safety, and design integration to make the system suitable for real-world use.
As development continues, attention will focus on material choices, electromagnetic shielding, and regulatory compliance to ensure consistent performance and user safety. The progress from prototype to practical installation will determine how broadly this kind of room-based wireless power can be deployed beyond experimental settings.
