Tracking at the speed of light

This sports top is designed to measure your movement without the need to strap on multiple gadgets.

The top is made from XelFlex, a fibre optic thread. Light can be pulsed through the fibres so an electronics pack can detect how the light is bent as the wearer moves, and then report back to a smartphone.

Designers Cambridge Consultants say the technology could be used for fitness and sports coaching, as well as to help with physiotherapy following an injury.

Mind games

Muse is a brain-sensing headband that is billed as helping you improve your concentration and reduce stress.

The band detects electrical signals in the wearer's brain and works with a smartphone app to give them feedback about how agitated their mind is.

Users can complete exercises to help them relax and focus their thoughts, with the goal of learning techniques to keep their mind settled and free from distractions.

Peak fitness

The Basis Peak smartwatch provides sensors to measure heart rate and activity - both daily exercise and sleep patterns.

An Android and iPhone app allows users to chart their stats and progress towards daily and weekly goals, such as their target number of steps.

Since it is designed to be a sleep tracker battery life is important, and its makers claim it can last for four days.

Lightweight monitor

Jawbone makes a series of wearables that track daily movements and sleep.

The UP series of trackers will feed data to a wide range of smartphone apps aimed at letting people monitor their health, as well as an official UP app for Android and iPhone handsets.

Hassle-free tracking

These earbuds will supposedly track your fitness without the need to charge an extra gadget.

Able to keep tabs on both your heartrate and activity, the BioSport headphones from SMS Audio sip the power they need from that provided by the audio jack.

Stats gathered by the buds can be tracked using the RunKeeper app.

Standing out

Designed for the safety-concious cyclist, VisiJax Commuter jackets feature turn indicators on the sleeves and bright LEDs for visibility at night.

A phone on your wrist

Burg Wearables smartwatches can make phone calls without having to be connected to a phone, as they accept SIM cards.

However, the watches can also be tethered to Android handsets and iPhones via Bluetooth.

Models offer varying features, including music and video playback, a voice recorder and a step counter.

Half headphones, half necklace

Samsung's Gear Circle are wireless Bluetooth headphones that try to offer more than your average buds.

The head gear includes a microphone to make calls, a vibrate function to signal incoming messages and a magnetic clasp that allows them to be worn as a necklace.

Samsung claims a battery life of nine hours.

Samsung Gear S

The Samsung Gear S smartwatch received a mixed review from TechRepublic's sister site CNET.

The wrist-mounted display was praised for its big and bright display, decent battery life and built-in 3G or wi-fi connectivity.

However, less impressive was the need to pair it with a recent Samsung smartphone to install apps and the limited selection of software compared to Android Wear devices.
