Robert de Saint Phalle submitted a new concept to Yanko Design that incorporates all the usual fitness measurement technologies in a necklace. The first of its kind that we have seen and Robert hopes the Arc Necklace will track temperature and EKG as well as outside temp, UV exposure and air quality. Air quality is a big concern across the world, and this sort of design would be very welcome. Incorporating headphones and bluetooth wireless streaming, this sort of design could certainly catch on provided it doesn't bounce or irritate with sweat build-up / friction. Good luck Robert!
