Apple is working on a wearable smart ring with an expandable design that could potentially offer similar uses as Apple Watch, except its worn around a finger rather than the wrist.

The expandable design could let the ring stretch out in accordion style from the form of a piece of jewelry to something that looks like a finger tube. The larger setting would leave room for things like sensors or even a foldable display. No matter what powers it unravels, though, there's no denying this design is weird.
The Echo Loop is not a full consumer product yet, only accessible via an invite from Amazon itself, but it shows a push to experiment with wearables and it only makes sense that Apple would through their hat in the ring. (Sorry, truly.)
Except in Apple fashion, the patent images we're seeing suggest something more forward-thinking. It appears the expandable ring could function as a controller of some kind for certain iOS devices. For example, the Apple smart ring might act as a haptic glove replacement that can communicate with the future iPhone 12.
Haptic sensors could be embedded within the extendable frame, and straining them with a bend of a finger could translate to gestures for operating external devices. In addition, Apple proposes in the patent that the ring could sport rotatable buttons and other physical input elements on the main ring housing.
Keep in mind Apple patents these types of ideas all the time, and very few actually make it to the consumer. But we already have the Echo Loop and haptic Tap Strap 2 Keyboard with gesture controls, so an Apple smart ring certainly can't be discounted as being the company's next big thing.
Calling it a replacement for the Apple Watch 6, though, is probably a stretch.
