Wireless Charging with Metal Devices
Qualcomm's new technology allows devices with metal exteriors to charge, even away from the charging mat. The new method of wireless charging also allows for multiple devices to charge at the same time.
If hauling around power chargers seems a practice that should be relegated to the early 2000's, that's because it is: wireless charging is here to stay, but designers are still having difficulty navigating practical hurdles. One of these hurdles is that wireless charging hasn't been compatible with devices with metal exteriors, and that's a problem, especially since so many manufacturers use metal alloys to increase durability in their products.
But that problem is finally resolved: Qualcomm has just made itself the first company to enable wireless charging for devices with metal exteriors. The technology, Qualcomm® WiPower™, operates at a frequency that is more tolerant of metal objects, so cases and keys and coins won't affect charging capabilities, and devices don't have to make physical contact in order to charge. It looks like a small flat black mat that can be built into furniture, so that setting a device on a surface like a coffee table can actually charge its battery.

"QTIs engineering advancement eliminates a major obstacle facing wireless power and opens up the continued adoption of this desirable feature to a much wider range of consumer electronics and use cases."-- Steve Pazol, General Manager of Wireless Charging, Qualcomm Incorporated
WiPower™ utilizes Near Field Magnetic Resonance technology and other devices can be charged simultaneously, even if they have different power requirements. Devices can be stacked or even held away from the mat and still charged.
From a design standpoint, this is compelling, as now unsightly cables can be eliminated and users can operate their devices away from the mat while they charge. From a technical standpoint, however, the new technology opens up an entirely new array of compatability possibilities. The era of going completely wire-free may be upon us.
A revolutionary initiative. Hope more advancement in the wireless power transmission technology by guys like you.Good luck☺
