Optimized ultra-low power sensor-enabled RFID data logger for pharmaceutical cold chain

This work presents an ultra low power, high sensitivity, high memory utilization, sensor-enabled, battery-assisted passive tags (BAP) as a data logger for pharmaceuticals cold supply chain. The BAP tag monitors the pharmaceutical products conditions during transportation and storage. As proof of concept, the BAP tag was developed to monitor only the temperature, but other sensors as light, moisture and vibration could also be applied. The development includes a different BAP tag architecture survey using low power techniques and smart memory management.The developed BAP tag consumes 1.9 μA in idle mode, 12 μA in Active mode, has -24.5 dBm sensitivity and can store up to 32.7k measurements using a 128 kbits memory.
