Smart sensor labels for food traceability and waste reductionThis project aims to develop a novel sensor label that integrates both colorimetric sensing and QR code technology for enhanced food traceability. The QR code stores critical supply chain data, detailing the journey of the food item from origin to shelf. In parallel, the embedded colorimetric sensor reacts to contamination by changing colour, offering a visual cue of food safety. These dual-function labels are designed to be low-cost, easily integrated into packaging, and accessible across all stages of the food supply chain.
