Some wearable tech is pretty new and innovative.

But the idea itself? Nope.

This picture proves that wearable technology is actually a fairly ancient idea - and no we're not talking about wristwatches.

The picture shows a tiny abacus silver ring dataing from 17th century China.

The Qing Dynasty ring is a fully functional abacus, which is smaller than a human thumb but which is just as useful as a full-size equivalent.

It's 1.2 centimetres long and 0.7 centimetres wide.

The calculating tool was a vital piece of equipment at that stage in Chinese history, and can still be found throughout the world, especially in education.

As this report makes clear it's not quite a computer, but it's a great example of how computational tools have always been needed on the move.
