Implementation of RFID Sensors for Monitoring of Bridge Deck Corrosion in Missouri

This work involves the implementation of a new Radio Frequency Identification (RFID) sensor that researchers developed at Oklahoma State University. The sensor uses an Atmel low-frequency RFID transponder. Initial versions used the metal on which corrosion was to be detected to connect the RFID chip to the antenna. If the connection eroded, the RFID transponder would stop working, indicating a potential problem. The second generation of the sensor implements the technology where corrosion is determined by the loss of section on the sensor circuit. When the circuit is broken, that information is transferred to the RFID chip and the information is communicated to the reader the next time the tag is read. Laboratory efforts still need to correlate the sensor's sensitivity to the level of corrosion in the structure.
