Temporary Tattoo Will Warn You If You've Had Too Much To Drink
The marking measures alcohol in a person's sweat and provides a BAC reading to a Bluetooth-connected phone
A team of researchers at the University of California, San Diego (UCSD) have created a temporary tattoo which, when working in tandem with an electronic board attached magnetically to the print, can measure alcohol and/or ethanol in a person’s sweat. By delivering a harmless drug called pilocarpine which generates sweat on the surface of the skin, the tattoo is able to draw a large enough sample to provide an accurate reading delivered via Bluetooth.
Though breathalyzers are a similarly non-invasive test of blood alcohol concentrations in the blood, false readouts make the method a faulty option in the presence of other options such as this tattoo. Conversely, the tattoo system works in near real-time according to its creators, and delivers more accurate results.
