RayNbow: Sun Exposure Tracker

Wearable technology nowadays is a huge trend and many companies want to add them to their collections, but when you ask people about it they say they do not like to have a sporty LCD with unwanted notifications on their wrists, they prefer something subtle and passive. RAYnbow is a piece of jewelry enhanced by technology to have a dual function as a stylish bracelet that has health benefits. RAYnbow has a UV sensor and array of baguette cut gemstones with LED lights underneath them that light up one by one in a gradient color when the skin is exposed to sun. So the user by looking at her bracelet and the number of gemstones lit up with color (light tan color for first steps to dark tan color in last steps), understands how much harmful UV she has received and decide to cover the skin or reapply sunscreen.
