Wearable Sensor-Enabled Meat Packaging For Freshness Monitoring and Assurance

This paper presents a wearable sensor-enabled lab-made packaging (donated as a prototype) for monitoring meat freshness. It highlights the evaluation of printed and wearable sensors created using advanced printing methods. With superior performance and durability, these sensors precisely detect hydrogen sulfide (H
2
S) gas in part per billion (ppb) levels, temperature (Temp) between −20°C and 80°C, and relative humidity (RH) between 10% and 90%. Thorough testing on fresh and expired meat products validates the effectiveness of these sensors, emphasizing the importance of comprehensive evaluations across different meat types and environmental conditions. Integrating these state-of-the-art sensors into packaging systems facilitates real-time and non-invasive monitoring, enhancing decision-making processes and elevating food quality assurance standards. Our commitment to sustainability drives innovation, fostering a more resilient and environmentally conscious future in the meat supply chain. These advancements aim to revolutionize food safety practices and inspire industry-wide transformation.
