Corrosion-related failures are usually a surprise; perhaps they could have been avoided if a real-time
monitoring tool was in place. However, collection of data in remote places is a necessary function of a
successful corrosion sensor network. For example, pipelines running through mountainous and
forested regions in the wilderness of Alaska are just as susceptible to corrosion and integrity threats as
those running parallel to subway tunnels in New York City, though accessibility may be easier in New
York. Corrosion of materials is perhaps the biggest threat to the integrity of complex systems. Ocean
vessels, pipelines, bridges, off shore drilling platforms, and wind turbines are a few of many structures
that may be subjected to the potentially debilitating effects of corrosion. In this work, several structural
integrity sensing techniques are illustrated. A method to detect coating disbondment is described. In
addition, a radio frequency identification (RFID) sensor for detection of moisture is developed and the
results are presented. Finally, a wi-fi motes-based corrosion monitoring system in use for coating
monitoring in a field test is described.
