What’s the bet you could beat an artificial tongue?
Can you do this?
• Pick up on differences between the same brand aged in different barrels, with more than 99 per cent accuracy?
• Tell the difference between those aged for 12, 15 and 18 years?
The tongue has metal taste buds, and measuring how they absorb light reveals the differences.
The artificial tongue could be used to ‘taste’ virtually any liquid, detecting counterfeits, and may be used in food safety testing and quality control.
