Here is a concept showing what could be a new bracelet by Samsung named  'S-health' , this comes after Samsung's big push with the health and fitness theme within the Samsung Galaxy S4 so it's quite probable that Samsung will develop this further. This certainly looks great and something that might just come our way. The concept is based on Tizen and imagined by Rebie Gutierrez.

Here are the concept features below: 

• 3.2 "widescreen OLED display Youm
