The researchers μηχανικοί στο National Institute of Biomedical Imaging and Bioengineering της Californias created an experimental tattoo that if you drink too much sends a warning message to mobile your phone to prevent you from driving.
This is a temporary one tattoo which contains a sensor that detects alcohol levels in your sweat and through bluetooth alerts your smartphone when you have surpassed higher levels of alcohol.
Sheila Selimovic (Seila Selimovic), Ph.D. and director of the National Institute of Biomedical Imaging and Biomechanical Program, said:
"It looks like a temporary tattoo, but it 's actually a biosensor with a fairly flexible wireless device built into it. An ingredient releases a chemical that stimulates sweat on the skin under the tattoo. "Another component detects changes in the electrical current that flows through the sweat produced, which measures alcohol levels and sends them to the user's cell phone."
Measuring alcohol from sweat isn't new technology, but the speed at which this new device is shipping is signalto your smartphone (about every eight minutes) is vastly superior to the two or three hours taken by its predecessors.
