Beer tasting with a robotic twist
PARIS (AFP) - Spanish researchers have created an electronic "tongue" capable of distinguishing between beer varieties and their alcohol content.
The artificial organ was accurate nearly 82 per cent of the time, said its creators - and could be the first step towards developing robots with a sense of taste.
The taster was made using 21 electrodes, each responsive to different chemical compounds such as ammonium, sodium, nitrate or chloride, according to researchers from the Autonomous University of Barcelona.
Exposed to beer, the electrode bundle yielded chemical data that could be analysed for patterns with which to identify the different brews.
