Wireless charging. To some, it's a dream. To others, it's a reality. But no one would argue that it's as advanced as it should be. PowerMat has proven that with accessory cases and a plugged-in mat, one can "wirelessly" charge their cellphone. But it still requires physical contact, and the base station still has to be plugged into a wall. It's not hard to see the holes in the theory, and while it's a step in the right direction, this isn't the idea we had in mind when dreaming of wireless electricity a decade ago.

Announced today over in Japan, Fujitsu has developed new technology for the design of "compact, high-efficiency wireless charging systems." These will reportedly rely on magnetic resonance-based wireless charging systems that can simultaneously recharge various types of portable electronic devices, and the company seems pretty proud of their invention. According to Fujitsu, the technology not only promises more compact and more efficient power transmitters and receivers, it also offers the ability to design charging systems in 1/150th the time currently required. Also, it paves the way to integrating compact wireless charging functions into mobile phones and enabling multiple portable devices to be charged simultaneously without any restrictions on their position with respect to the charger.


This sounds like a real advancement due to the embedded nature, but future details are being withheld until the Institute of Electronics, Information and Communication Engineers (IEICE) opens later in the week.

Nice, but doesn't this still have to be plugged in to the wall? :D or does it just produce its own energy somehow O.o

It looks like an inductive charger and that would have to be plugged into a power source. I wonder about stray radiated energy and how it would affect you and your pets. Would it play nice with other electronics in the room?

Dogs are great judges of character, and if your dog doesn't like somebody being around, you shouldn't trust them.
