Disney Research Made a Room That Will Wirelessly Charge Any Phone
“As a society, we’ve been almost desperate in our need to recharge our phones and laptops and locate the cords and electrical outlets to make it happen. Now scientists at Disney Research have a found a way to turn an entire room in a wireless charging space. Their method, called quasistatic cavity resonance, has the potential to make wireless electrical power as ubiquitous as Wi-Fi. Just walk into a room and your device starts charging.”
Quasistatic Cavity Resonance for Ubiquitous Wireless Power Transfer
“Wireless power delivery has the potential to seamlessly power our electrical devices as easily as data is transmitted through the air. However, existing solutions are limited to near contact distances and do not provide the geometric freedom to enable automatic and un-aided charging. We introduce quasistatic cavity resonance (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.”
How Does Wireless Charging Work?
“Essentially, wireless charging uses a loop of coiled wires around a bar magnet – which is known as an inductor. When an electric current passes through the coiled wire, it creates an electromagnetic field around the magnet, which can then be used to transfer a voltage, or charge, to something nearby, Resnick said.”
