Disney Research says its new quasistatic cavity resonance (QSCR) technology offers a way for mobile devices to wirelessly charge themselves by taking power from magnetic fields generated by purpose-built structures.

The Disney engineers employ a magnetic resonator coil to emit these fields.

Their experiments demonstrated the QSCR technology could provide power to small coil receivers in almost any position with 40% to 95% efficiency in a 16×16x7.5-ft. room with a floor, ceiling, and walls of painted aluminum sheet metal. Disney says a maximum 1,900 watts can be safely conveyed between transmitters and a coil receiver in a mobile device, "enabling safe and ubiquitous wireless power."

"Ultimately, QCSR-based wireless power offers a viable method for eliminating the wires and batteries that have limited many innovative solutions in the industrial, medical, and consumer electronic spaces while providing an unprecedented amount of spatial charging freedom," according to Disney.
