AI ‘Tongue’ Can Tell the Difference Between Coke and Pepsi
Researchers at Penn State have developed an electronic “tongue” that uses AI to distinguish between Coke and Pepsi with impressive accuracy. The device, made from graphene connected to a neural network, can detect various liquid compositions, including different types of sodas, like diet and regular.
This AI-powered tongue isn’t just limited to sodas—it can also analyze diluted milk, coffee blends, and fruit juices. It boasts an 80% overall accuracy rate, and when it comes to fruit juices, it identifies types with 98% accuracy and can even determine the fruit’s age 99% of the time.
Beyond just flavor profiling, researchers say this technology could eventually assess a product’s freshness and identify harmful contaminants in food.
