To implement an innovative RFID Sensor into new bridge deck construction to collect data during monitoring to study both the reliability and field performance of the sensors in-situ and under laboratory conditions. | ||||
Project Abstract |
This work involves the implementation of a new 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. |

Technology Transfer Activities |
Results of the proposed work will be available for use in the NUTC technology transfer activities (i.e. Newsletters, Annual Conference) as well as publication in conference and/or journal publications. |
||||
Project Deliverables |
The project deliverables will include a summary report of the in-situ application and technology transfer activities. | ||||
Anticipated Benefits |
This work will provide the first in-situ based data collection on the new RFID sensor and will also further assist in the correlation of laboratory and field based correlation of corrosion data collected from the RFID reader. |
