Alcohol and tattoos

A wearable device, resembling a tattoo applied to the skin can measure the amount of ethanol excreted in sweat and send the data to a smart phone. The device could be used by drinkers to monitor their intake or in a regulatory or rehabilitation setting. The device is being developed by a team of scientists and engineers from the University of California, San Diego in La Jolla, USA led by Seila Selimovic.
