Researchers have designed a tattoo to tell you how drunk you are

If there’s one thing our drinking adventures have taught us, it’s that tattoos and alcohol are never a good mix.

Until now that is. Researchers at the University of California have developed a temporary tattoo which can analyse your sweat and send a message to your smartphone to tell you how drunk you are. Yes, really.

Admittedly, the tattoo doesn’t really look like a tattoo. First tattoo paper is applied to your skin, and then a tiny circuit board smaller than a piece of gum sits on top. A small current is generated to trigger sweat, which a sensor then uses to determine your blood alcohol levels.

“Right now, the tattoo is designed for one-time use,” says University of California professor, Patrick Mercier. “Place, detect, dispose.”
