LAS VEGAS -- More than 170,000 people are here at the annual Consumer Electronics Show (CES) to see the latest in gizmos and gadgets.

While technology can come in all shapes and sizes, in the health world, less is more.

Companies have scrambled to make devices that can be worn wherever you go. And as wearables get smaller, the roles they can play in our lives can get larger because these sleek devices connect to tablets, smartphones and the web.

Most have the ability to upload biometric data to the Internet for users and their doctors to monitor.

We checked out some of the innovative health wearables on the floor at CES 2016.
