Breathaleye is a conceptual app based on the theoretical technology ‘Metalens’. This is a smart lens that can be used to track all kinds of human behaviour, for example health and fitness. The core function of the Breathaleye app specifically was to measure the BAC (Blood Alcohol Content) using the smart lens to show the user whether they are safe to drive or not. This function works much like a breathalyser, only in real time and is available on your phone.
