New Temporary Electronic ''Tattoo'' Warns you if You've had too Many

The future of knowing when you're a little bit too drunk just got a lot trendier.

We've all had that one drink... That one drink that you weren't planning on having with your friends because you have to drive home that night. And then, magically of course, three or six more drinks find their way into your body and you're sitting there telling yourself that it's the last one and it's time to sober up because swerving into a ditch just isn't that cool. 

Thinking bout that drink. #onetoomany

Then you think, I'll just drink some water and leave when I feel good. Well, unfortunately, most of the time even when you think you're good, your blood-alcohol level thinks otherwise.

However, thanks to a group of researchers at the University of California San Diego, we can now be a lot more sure of our choices while still avoiding the uncomfortable breathalyzer test or the annoying pricking of the finger trick. 

The researchers designed a temporary electronic tattoo that can evaluate your blood alcohol concentration by absorbing your sweat. The small chip-looking tattoo then sends the information through bluetooth on your cellphone and tells you when you're over the limit.

How does it work?

First of all, the small tattoo is composed of a sticky transparent strip, which is attached magnetically to a flexible circuit board.

The circuit board prints electrodes onto the commercial tattoo paper which generates a small current for a few minutes. The current then causes the tattoo to release a thin layer of gel that releases a drug called pilocarpine onto our skin. 

This drug causes the wearer of the device to sweat. The sweat is then measured by an electrochemical sensor and the data is transferred to your phone through bluetooth. 

The process may seem complicated, but the results are what we are interested in anyway. It's a brilliant invention which can eventually save your life. 

Round of applause for the researchers at UCSD
