“The wireless power transmission technique known as magnetic resonance was widely known by a paper published in 2007 by Prof. Marin Soljacic of MIT,” Jack Purcher reports for Patently Apple. “Unlike the magnetic induction method that was invented 100 years ago, it has no restriction in distance. So you could charge devices without the need of a charging board of any kind.”
“It’s this attribute that it has been attracting popular attention as the next-generation wireless power transmission technique,” Purcher reports. “One of the first wireless charging patents designed for the PC using a magnetic resonance system was Apple’s November 2012 patent application which was granted earlier this month. Earlier in September we reported on a new more detailed patent filing from Apple on this very technology. We noted as far back as February that Apple and Samsung were in a race to be first with a next generation wireless charging system and last month we reported on Samsung’s latest move on this front with a 3D orientation-free wireless power transfer patent.”
“Samsung and Qualcomm will likely be first to bring magnetic resonance solutions to smartphones in in late 2014 or early 2015, though Apple could always surprise us on this front,” Purcher reports. “Now a new report suggests that magnetic resonance technology could lead to the cordless home over the next 3-5 years.”
