Orii builds a smart ring that turns a fingertip into an earpiece

From Orii smart ring turns your fingertip into a Bluetooth earpiece

you wear the ring on your index finger, and when it vibrates with an incoming call, simply lift your hand up, touch your fingertip on a sweet spot just before your ear, then chat away. An earlier crowdfunding project, the Sgnl smart strap (formerly TipTalk) by Korea’s Innomdle Lab, had the same idea, but it has yet to ship to backers long after its February target date this year.

The Orii is essentially an aluminum ring melded to a small package containing all the electronics. The main body on the latest working prototype came in at roughly 30 mm long, 20 mm wide and 12 mm thick.
