Sensor integrated RFID tags driven by energy scavenger for sustainable wearable electronics applications
2016
The use of radio frequency identification (RFID) technology for the automatic identification and communication of physical parameters with on board integrated sensor attracts vast applications on a large scale ranging from mobile healthcare to logistics, supply chains, robotics and many others. Recently, sensor RFID tags have been considered in wearable electronics. However, these devices are still empowered by a battery. In this paper, we proposed and designed a self-sustainable sensor integrated RFID tag for wearable electronics applications. A polyvinylidene fluoride (PVDF) integrated dual-gate thin film transistor (TFT) was used to harvest energy from daily human activities such as arm/finger movements. Numerical analysis and preliminary results of such energy harvester was reported in addition to system design of sensor integrated chip-based active RFID tag.
