    I was looking at some smart rings and became interested in how they work. They are often wirelessly charged and have bluetooth so that you can be connected to wifi for instance and look at your Twitter feed etc. The thing I don't understand is how they fit both the bluetooth and battery inside them? Does anyone here know what kind of batteries they have (and if it is possible for one to design and order them) and what kind of bluetooth they use (must be the tiniest if they can fit it in the ring). I can't find any specifications or details on the companies that sells them.
