TDK develops ultra-thin receiving coil unit for wireless power transfer
Technology ( 2 )
TOKYO —
TDK Corp said Tuesday it has developed a wireless power transfer coil unit designed for Smartphones and other mobile devices. The receiving coil designed for integration in Smartphones and similar represents an industry-leading achievement, featuring a thickness of a mere 0.57 mm.
The coil unit not only is ultra thin and lightweight, it also is highly resistant to shock and therefore provides excellent reliability. Furthermore, in spite of its 0.57 mm profile, the coil’s design minimizes the tendency toward rising resistance and achieves a power transfer efficiency that allows clearing the requirements of the WPC “Qi” standard. The low height of the unit is a key aspect for use in Smartphones. At this point, output current is on the order of 0.5 to 0.6 Amperes, but an even thinner 0.50 mm type with equal or better output current is already in development, with a view towards starting mass production in 2013.
As Smartphones incorporate more and more functions, their power consumption also tends to increase, making charging of the battery a more frequent requirement. With the aim of establishing an infrastructure environment that allows easy charging anywhere at any time, the WPC and other promotional organizations are working towards the standardization of wireless power transfer.

It's only a matter of time until devices like these get implanted into the empty heads of the zombies who are unable to stop texting and playing games from the moment their eyes pop open in the morning.

whilst one accepts that overdoing phone time is common, how is it much different than any other fiercly watched hobby or practise If we applied that logic fairly to everything we wouldnt have experts, professionals or even amateurs
