Quick Summary
Xiaomi has filed a patent for a smart ring that has an auto-adjusting size.
The patent was noticed by 91Mobiles and while it doesn't mean the smart ring will appear in the flesh at any point, it's an interesting concept.
Smart rings are all the rage at the moment, which isn't a surprise when you consider what they are capable of. Small and discreet whilst still offering heaps of data, they are an excellent solution for people that want to keep track of their health and fitness but perhaps aren't huge fans of smartwatches.
