As phones replace more and more devices, even S wallets, making sure the phone is always charged is becoming more and more important. While portable power is the preferred solution for now, Samsung is planning to design more convenient products in the future. According to a patent filed by Samsung with the South Korean Patent Office, a very peculiar little device has been revealed that describes a “ring” that can charge a smartphone.
However, the device is not powered by a battery wrapped around the finger. Instead, the disk in the ring generates an electric current through the movement of the hand. In layman’s terms, there is a miniature generator inside the ring.
But that’s not all. According to the patent, in addition to kinetic energy of motion, the ring can also convert heat from the body into electricity.
Of course, there will also be a small battery to store the electricity generated and then transmit it to the phone. This is where the ring comes in handy. When the user uses the phone, the ring will be able to charge the phone without the need for a cable or charger.
Usually when we are holding a mobile phone, the middle finger with a ring on it can be directly connected to the wireless charging coil.
Of course, the “charging ring” has a number of challenges to overcome before it can actually be launched, mainly related to the size of the components.
Converting kinetic energy into electricity is nothing new, but the problem is that mobile phones require more battery life, so it remains to be seen whether this little “ring” device will work.
