Radio frequency identification (RFID) based corrosion monitoring sensors Part 1 – Component selection and testing

Cost-effective radio frequency identification (RFID) transponders (tags) were investigated for use as wireless corrosion monitoring sensors. Performance metrics of read rate, received signal strength indicator, and minimum activation power were established for the as received tags. The effects of orientation, distance between transceiver (reader) and tag, and a metallic backing were evaluated using these performance metrics. Laboratory tests to …
