From dresses and coats to specs and bands, we look at ten of the best wearable devices this year.
3. Safety bracelet
Cuff, a San Francisco-based startup, has released a collection of bracelets, necklaces and key chains that it claims keep users safe.
There is an accompanying waterproof black tracker called Cufflinc that slots into any of the jewellery and links to a smartphone app via Bluetooth.
The device would allow users to send alerts out to family or friends in an emergency or simply let them know when they’re trying to get in touch.
Deepa Sood, co-founder of Cuff, in a statement said: "The new Cuff collection wearables are more chic than geek, wrapping smart technology into elegant, fashionable pieces that we all WANT to wear."
"We don’t believe that we should be forced to choose between smarts and beauty when it comes to wearable accessories."
The device, which costs between £30 and £100, is currently available for pre-order with shipments starting later this year.
4. Heart sensor bracelet
Canadian firm Bionym’s Nymi bracelet reads the unique pattern in people’s heartbeat to confirm who they are.
The bracelet has a built-in sensor to detect where they are and a HeartID that measures the cardiac rhythm tracked on an electrocardiogram, which differs from person to person.
It works by taking an electrocardiogram when the wearer touches it with the opposite hand, which then broadcasts a signal to a matching computer, device or car that confirms his or her identity and unlocks it.
Bionym hopes the hype around fingerprint scanning created when Apple unveiled its iPhone 5S will create excitement around the Nymi.
