RFIQ System Detects Food Contaminants

Nov-16-18 A new RFIQ system could make it easier for consumers to monitor food safety.

Developed by a team from MIT, the RFIQ system is based on a phenomenon called ‘weak coupling,’ in which the signals emitted by the RFID tag will change based on the contents of the product. By ‘teaching’ the tags which changes correlate to specific contaminants, the system can detect food safety issues and transmit the alert to a paired smartphone.

Currently, the team is working to build a library of potential contaminants and how the signals can be altered by the shape of the container and the environment. According to co-author and assistant professor Fadel Adib, "We want to democratize food quality and safety, and bring it to the hands of everyone."
