In this paper, we develop the novel force sensor system for structural health monitoring (SHM) using the 13.56 MHz band passive RFID. In SHM for buildings and apartment houses, it is important to measure the strain and the static load of the structural member covered with concrete or coating materials. In our system, we assume the force sensor-equipped passive RFID tag that has the A/D converter is placed in near the structural member in the covering materials. And then, from the outside of the covering materials the sensor signal is read without contact as well as the memory data communication to the RFID tag by the RFID reader/writer. So this force sensor system enables to measure the strain and the static load of the structural member covered with concrete or coating materials. In this system, power supply to the RFID tag and the force sensor is achieved by an electromagnetic induction system and therefore this force sensor system does not need battery inside the space covered with concrete or coating materials.
