The June bracelet by Netatmo is a designer accessory with a gemstone-like sensor that measures sun exposure in real-time and syncs with an iOS app.
Since the sensor doesn’t have a display, it provides information through the app. The app tells the user how much sun they are getting, what SPF sunscreen to use, and when to put on sunglasses or a sun hat.
Designed by Louis Vuitton and Camille Toupet, the glittering sensor can be detached from the bracelet and used as a brooch.
The bracelet is being demonstrated at the CES 2014.
