Electronic tongue can distinguish between 51 types of beer.

Photo: flickr/David, Bergin, Emmett and ElliottWish your tongue didn't have to work so hard? Behold, an electronic tongue (actually an array of ion-sensing electrodes), capable of distinguishing between 51 different kinds of beers with 81.9% accuracy and even predicting alcohol content. So the next time someone at a party hands you a red cup full of who-knows-what, just pull out your electronic tongue. You'll be the life of the party.Beer classification by means of a potentiometric electronic tongue. "In this work, an electronic tongue (ET) system based on an array of potentiometric ion-selective electrodes (ISEs) for the discrimination of different commercial beer types is presented. The array was formed by 21 ISEs combining both cationic and anionic sensors with others with generic response. For this purpose beer samples were analyzed with the ET without any pretreatment rather than the smooth agitation of the samples with a magnetic stirrer in order ...
