The beer brand Karhu, a Finnish brand of the brewing giant Carlsberg, has come up with a brand-new concept of a breathalyzer – or lickalyzer – in the form of a wristband.
During the Solstice festival, held in northern Finland in June, festival-goers wore two wristbands: one for access to the shows and another to test their blood alcohol concentration at any time.
And the device was very simple to use: you just had to peel back a strip to pass your tongue over it.
Designed by Promilless and backed by the Technical Research Center of Finland (VTT), this “lickalyzer” is equipped with very precise technology, capable of detecting traces of alcohol in the blood from zero to 0.05%.
The idea behind this innovation is to make it possible to check your blood alcohol level at any time in order to adapt your consumption, drink a glass of water, and especially, wait a while before taking to the road.
