Researchers extend range of wireless power transfer2014-01-13 09:25 by DanielaTags: Wireless
Researchers at Duke University's Pratt School of Engineering have developed a method of transmitted energy wirelessly over distances greater than the size of the transmitter and receiver. The team used metamaterials to create a "superlens" that focuses magnetic fields. The superlens "looks like a few dozen giant Rubik's cubes stacked together," according to information released by Duke University. "Both the exterior and interior walls of the hollow blocks are intricately etched with a spiraling copper wire reminiscent of a microchip" that interacts with the magnetic field to form a cone of more intense power.
Going forward, Urzhumov wants to drastically upgrade the system to make it more suitable for realistic power transfer scenarios, such as charging mobile devices as they move around in a room. He plans to build a dynamically tunable superlens, which can control the direction of its focused power cone. Read more -here-
