Wireless Passive Sensing Platform Based on RFID Technology for SHM Purposes

Abstract : Recently there are many attempts to use wireless communication and its capabilities in data acquisition from sensors, in SHM application. Beside typical active Wireless Sensor Networks (WSN), there are also attempts to develop sensor networks with passive nodes, using the advantages, provided by Radio Frequency Identification (RFID) technology. The main benefits of this solution are utilization of energy of the communication signal from the reader antenna for sensor circuit powering and possibility to place sensors in any places, including hard available and moving locations. Development of such sensing platform based on M24LR64E-R RFID chip working in HF band, suitable for working with different types of sensor - strain gauges, accelerometers, pressure sensors is presented. It is designed especially for monitoring helicopterÕs rotor blades. Entire energy needed to power the microcontroller, RFID chip, sensor and other circuit elements is supplied by the reader wirelessly, by using magnetic coupling between the reader and the sensing platform antenna. The paper presents a concept of the sensing platform, its first prototypes and investigation related to communication between the platform and the reader, as well as first experimental studies related to using this platform in different applications.
