Disney’s research arm has revealed plans to use Quasistatic Cavity Resonance (QSCR) to enable purpose-built structures to generate special magnetic fields able to charge electronic devices wirelessly.
Creating a magnetic static charge in the air, the QSCR system safely deliver kilowatts of power to mobile receivers contained within a certain range.
According to Disney Research, a quasistatic cavity resonator has been created, with field applications and power transfer efficiency validated against a series of measured results.
“Wireless power delivery has the potential to seamlessly power our electrical devices as easily as data is transmitted through the air,” said a statement from Disney Research.
“However, existing solutions are limited to near contact distances and do not provide the geometric freedom to enable automatic and unaided charging. We introduce QSCR, which can enable purpose-built structures, such as cabinets, rooms, and warehouses, to generate quasistatic magnetic fields that safely deliver kilowatts of power to mobile receivers contained nearly anywhere within.”
Following an experimental demonstration, Disney says a 54m³ room with QSCR can deliver power to small receivers in nearly any position with 40 per cent to 95 per cent efficiency in terms of charging. Analysis also shows that up to 1900 watts can be safely transmitted to a coil receiver enabling safe wireless power anywhere within the space.
