AIPIA World Congress 2022

Updated: Feb 28

14-15 November 2022, Amsterdam, Netherlands.

AIPIA or Active & Intelligent Packaging Industry Association is a global non-profit trade association that represents companies and organizations involved in the development, production, and application of active and intelligent packaging solutions. AIPIA serves as a hub for companies and professionals in the active and intelligent packaging industry, fostering collaboration, knowledge exchange, and innovation. The association organizes events, conferences, and workshops to promote the latest developments and applications in the field. It also provides resources, research, and networking opportunities for its members, encouraging advancements in active and intelligent packaging technologies.

Dr. Pichaya Pattanasattayavong, CEO and CTO of Cleantech & Beyond, was invited as a speaker in the topic of, "Thermoresponsive materials enabling battery-free, NFC/RFID temperature-monitoring labels".

Smart labels that can detect a critical temperature threshold are in demand for tracking temperature-sensitive goods in modern logistics. The visual temperature indicators are widely used, but they require manual inspection of individual tags. In contrast, RF-based devices require a power supply (data loggers), thus not suitable for item-level tracking. Some temperature-sensing passive NFC/RFID tags are available; however, they can only report the temperature when communicating with an RF interrogator. Our team has developed a new sensor component based on thermoresponsive materials that can be integrated with conventional passive NFC/RFID labels.
The sensor operates continuously based on the physical reactions of the thermoresponsive materials, eliminating the need of an external power source. Crucially, the status of the sensor is specifically engineered to be irreversible: once a temperature threshold is exceeded, both the visual appearance (color) and the electrical state of the sensor are irreversibly changed. Essentially, this allows the sensor to store 1-bit memory of the thermal history (within limit vs limit exceeded) and can output both visual and digital indicating signals. The sensor’s properties enable the realization of smart temperature-monitoring, battery-less labels for item-level tracking of temperature-sensitive goods such as pharmaceutical and cosmetic products.
