Electrical engineers at the University of California, San Diego, have developed a dual frequency wireless charging platform that could be used to charge multiple devices, including smartphones, smart watches, laptops and tablets, at the same time, regardless of which wireless standards or frequency each device supports.
"To our knowledge, this is the only multi-standard wireless power transmitter that's been shown to operate simultaneously at two different frequencies with high efficiency," said Patrick Mercier, a professor in the Department of Electrical and Computer Engineering at UC San Diego who led the study published in the journal IEEE Transactions on Power Electronics, reports Phys.org.
The new proof of concept study addresses an issue that affects existing wireless technology: incompatibility between the three competing wireless standards Qi, Powermat and Rezence. The researchers say they developed a technology that is universal and supports all of the standards, so it won't matter which one a device supports. Article
