When considering a monitoring technique to track corrosion, the most significant parameters related to corrosion in a given application must be selected. In some cases, tracking of changes to the environ- ment may be sufficient, while in others direct knowledge of structural corrosion may be preferable. Corrosion sensing methods may be divided into two main categories; those that react to environmental corrosivity, and those that respond to actual degradation of a structure of interest. This paper reviews work presented over the last decade in the research and development of sensors for monitoring and measuring both environmental corrosivity and structural corrosion, along with some examples of field applications.
