rfid cold chain failuresCongratulations to our Ph.D. students Federico Vivaldi, Andrea Bonini and Noemi Poma for their scientific publication entitled “A temperature-sensitive RFID tag for the identification of cold chain failures” in the journal “Sensors and Actuators A: Physical”.

Quality and safety of the cold chain undergo strict international regulations that identify storage and shipping temperatures. In fact, the improper handling and transportation of temperature-sensitive products such as food and pharmaceuticals may have harmful effects on human health and a negative economic impact. A passive RFID tag modified with a copper-doped ionic liquid was used to detect the crossing of a temperature threshold (8 °C) during the shipping of medical products. The tag was insensitive to humidity variations and irreversibly changed its status once temperature exceeded the ionic liquid melting point, which can be tuned by changing the concentration of dopant.
