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.
