Scientists have created the first artificial tongue that can sense and identify flavors entirely in liquid environments — mimicking how human taste buds work.
The achievement, described July 15 in the journal PNAS, could lead to automated systems for food safety and early detection of diseases via chemical analysis, the researchers say.
The technology could also be integrated into lab equipment for chemical analysis of liquid samples. The researchers also see it as a step toward “neuromorphic computing” — AI systems that mimic the brain’s learning process.
