Printed electronics measures your sweat

Scientists of the University of California have developed new technology to simply measure one´s alcohol percentage from sweat. The flexible wearable sensor measures the alcohol in the blood in near real-time. Every 15 minutes the system reflects a value, something that previously took 2 hours. The system consists of printed electrodes, fed by a printed circuit board that sticks to the skin. The system wirelessly sends the information to a computer or smartphone.
