Food quality monitoring by portable electronic nose based on organic field-effect transistors

Determination of food freshness is the most ancient role of the sense of smell while still being a challenge for compact electronic nose devices. Fast, sensitive and reusable sensors are long-awaited in the food industry to replace long and expensive bacteriological methods. In this work, we present some new results on the emerging application of electronic noses based on Organic Filed-Effect Transistor to the problems of food spoilage detection and its quality estimation.
