Sensors today are smart, rugged and can accurately measure a wide range of elements and physical parameters. Devices can be integrated and microengineered onto a chip offering high functionality, accuracy and good reliability. By combining CMOS and sensor technologies, a small wireless sensor can deliver broad based corrosion monitoring in crucial applications. Corrosion sensors have been used to detect coating defects and monitor coating degradation. Robustness and longevity were evaluated in various environments to simulate typical usage and storage conditions. Preliminary assessments identified vulnerable areas in the sensor development.
