Scientists have created an electronic “tongue” they say uses AI to differentiate between the sodas Coke and Pepsi — with the potential to detect the chemical makeup of and the differences between liquids beyond human abilities. Researchers at Pennsylvania State University suggested that the device’s unique sensors could be used to determine whether food is fresh or contains harmful contaminants, such as omni-present PFAS, or “forever chemicals.”Penn State researchers have created an electronic “tongue” that uses AI to accurately tell the difference between the sodas Coke and Pepsi. Saptarshi Das Lab/Penn StateThe “tongue” was developed using graphene, a single layer of carbon atoms in a honeycomb pattern, that is connected to an AI neural network. The findings indicate that the creation could determine a product’s freshness and confirm whether risky contaminants are present in food. While the device was tested on Coke and Pepsi, it could be used to determine whether food is fresh or contains harmful contaminants, such as PFAS “forever chemicals,” researchers said.
