Smartphone batteries have gone a long way but even in 2020, battery anxiety is something many people have to deal with on a daily basis. As our phones replace more and more devices and even our wallets, it becomes increasingly important that they have power at all times. And while carrying a power bank or a battery case is the go-to solution today, Samsung envisions something a lot more elegant for the future.
A patent filed by Samsung at South Korea’s patent office was published today, revealing a very curious little device. The patent was quickly spotted by GalaxyClub and describes a ring that is meant to charge your smartphone.
The device isn’t powered by a battery wrapped around your finger, however. Instead, a magnetic disc inside the ring moved around by the motions of your hand is creating electricity. Basically, there’s a tiny generator embedded in the ring. But that’s not all. Apart from the kinetic energy of your movements, the ring will also be able to transform your body heat into electricity, according to the patent.
