QUALCOMM Technologies has engineered a solution that allows devices like phones to wirelessly recharge, even if they have metal exteriors.
The solution uses Qualcomm's WiPower technology, and is designed to be compliant with the Rezence standard. It is the first announced solution to support wireless charging for metal devices.
Until now, it has been impossible to create devices with metal exteriors that can charge wirelessly.
“Building a wireless charging solution into devices with metal exteriors is a significant step for moving the entire industry forward,” said Steve Pazol, General Manager of Wireless Charging, Qualcomm.
“Today, more device manufacturers are choosing to utilize metal alloys in their product designs to provide greater structural support and, of course, aesthetics."
The new innovation will allow the continued adoption of wireless charging technologies o a wider range of consumer electronics and applications.
WiPower, as well as other technologies that meet the Rezence standard, operate at a frequency that is more tolerant of metal objects that come within the charge field. While previously this meant the technology was tolerant of objects like keys and coins in the charge field, the new advancement allows the ability to charge devices with metal casings at up to 22W.
Based on Near Field Magnetic Resonance technology, WiPower enables greater flexibility and convenience in wireless charging, allowing a wide range of compatible consumer-electronic and handset devices to charge without the need for precise alignment or direct physical contact.
