Penn State Researchers Develop 'Electronic Tongue' to Give AI Sense of Taste

Penn State researchers developed an electronic tongue that mimics human taste to make AI more emotionally intelligent.

The electronic tongue detects 5 basic tastes and has applications in AI diets and personalized restaurant offerings.

The electronic tongue combines graphene sensors to "taste" and molybdenum disulfide circuits to "remember" tastes.

Researchers aim to expand the taste range to mimic human tongue's 10,000 taste receptors.

This could enable future AI with emotional intelligence related to taste and other senses like sight, sound, touch.
