Even though smartphone batteries have improved dramatically over the past couple of years, they are still a major concern on long workdays. But as devices get thinner, accessories like powerbanks are also becoming more common. However Samsung there may be another, more innovative idea of charging devices on the go.
A recent patent filing by the South Korean tech giant revealed that the company may be working on a new wireless charger that can charge smartphones, and it doesn't look like the ones the company has sold in the past. It is a ring that is activated by the user's movement. In short, the device is not a small emergency battery to charge the phone, rather it uses a magnetic disk inside a ring that rotates when the user's hand is in motion.
This process generates electricity, turning the tiny product into a kind of mini-generator. But that's not the whole picture, as the device is also capable of transferring heat from the user's body to generate electricity, in addition to using only kinetic energy. According to the report PhoneArenaSamsung plans to use a small battery in the device to store the generated electricity before charging smartphones.
Charging the device is another interesting aspect of this patent, since the user will not be connecting the device via the USB port. Chances are, your phone will charge wirelessly when you use your device normally. This will mean that your finger should be in the higher position where the wireless charging coils are located to charge the phone. Keep in mind that this is just a patent and we may never see a product intended for the commercial market, but it does give an idea of possible future electronic accessories.
