Sensor Integration in an Rfid Tag for Monitoring Biomedical

RFID is evolving as a major technology enabler for identifying and tracking goods. RFID applications in biomedical area not only need to detect but also require monitoring and transmitting vital signals like heartbeat. The basic building blocks of an RFID tag for biomedical application are studied. This paper mainly focuses on the design and optimization of sensor that could be easily integrated in an RFID tag for remote monitoring of heartbeat signal. The sensor is based on the detection of capacitance variation when a heartbeat signal pressure is applied. The characteristics of the sensor are presented and this work would be very relevant for the sensing, remote monitoring of biomedical signals.
