Samsung just unveiled its first smart ring -- the Galaxy Ring -- at its Unpacked event in Paris, but details are already emerging about a possible successor.

A report from 91mobiles shows a patent application for something that looks an awful lot like a new version of a Samsung smart ring.

Samsung filed a patent for a "ring type wearable device" on May 16, 2024. The patent filing shows not only a drastically different design than the current Galaxy Ring, but significant additional features.

Instead of a totally circular ring, the new patent shows a more square outer layer with a round inner layer containing the device's sensors. The biggest addition, though, is two display screens that run along the sides of the ring. In the patent image, both screens display icons for different apps. Choosing an icon, 91mobiles says, likely displays relevant information on the other screen.

If these screens were to show workout stats and notifications, it means the ring would be much more interactive than all other smart rings currently on the market. The patent also shows ring sensors for Galvanic Skin Response, SPO2, PPG, ECG, temperature, and acceleration, plus a fingerprint sensor, which would be a big improvement over the current generation.

The patent also includes information about possible connectivity options, including Bluetooth, Wi-Fi, Zigbee, NFC, and MST, the technology that powers mobile wallets like Google Wallet and contactless cards.

Finally, the patent mentions plans for multiple ring sizes that would necessitate design and cost variations based on size. By way of example, it suggests 27 ring sizes available in South Korea and 65 ring sizes available in the US.

Of course, a patent doesn't necessarily mean the device will ever see the light of day. Even if it does, that day could still be years away.
