Wireless Antenna Sensors for Strain and Crack Monitoring

An ultra-low-cost RFID solution has been investigated for monitoring stress concentration and crack formation in structures. In an RFID (radiofrequency identification) system, the reader beams electromagnetic energy to the RFID tag/sensor, which receives the energy and reflects electromagnetic signal back to the reader. Therefore, the sensor is wireless and doesn't require battery power. When the RFID tag is under strain/deformation, the tag antenna shape changes and causes its electromagnetic resonance frequency to shift. This resonance frequency shift can be detected by the reader, and then used to derive the strain experienced by the RFID tag. Prototype sensors have been developed in collaboration with Prof. Manos Tentzeris's group in ECE and Prof. Roberto Leon's group in Roberto Leon's group in CEE at Virginia Tech.
