Could this be the ultimate taste testing device?
scientist Created an electronic “tongue” They say they are using AI to tell the difference between Coke and Pepsi sodas, and that it has the potential to detect chemical compositions and differences in liquids that are beyond human ability.
Penn State researchers used the device's unique sensors to determine whether food is fresh or contains harmful contaminants such as the ubiquitous PFAS (“forever chemicals”). He suggested that it might be possible to determine whether
“tongue” developed using graphenea single layer of carbon atoms in a honeycomb pattern, connected to an AI neural network.
The researchers mimicked the human brain's gustatory cortex, which deals with the perception of taste.
The device's sensors can detect different liquid compositions and distinguish between diluted milk, blended coffee, and fruit juice, as well as types of Coke and Pepsi (such as diet and regular meals).
Researchers claim an overall accuracy of 80% for tongue findings. Especially when it comes to fruit juices, it can identify the type with 98% accuracy and even pinpoint the age of the fruit 99% of the time.
The findings show that this creation can determine the freshness of a product and check whether dangerous contaminants are present in the food.
“Although corrective measures exist for food adulteration and contamination incidents, monitoring food freshness is more difficult because the chemical composition present in food changes over time and is complex.” read in researchhinting that the “tongue” may more effectively remove harmful ingredients. “Rotten food is dangerous to eat and has reduced nutritional value.”
The researchers further suggested that this new technology could “serve as a cost-effective platform for a wide range of chemical sensing applications in the food supply chain and beyond.”
