At Mobile World Congress recently we saw wearable technology from many of the big players, including Samsung's Gear smartwatches and Sony's SmartBandand Core life-tracker. But there were a host of other devices on show from less well-known brands, such as Huawei's TalkBand.

The focus in the current wearable market is clearly on wrist-mounted devices, whether they are smartwatches, fitness bands, or a combination of the two. The future of wearables isn't limited entirely to our wrists however. There are plenty more places on your person that manufacturers are keen to exploit with their latest piece of desirable tech.
