Publication number: 20150247815Abstract: A corrosion sensor to automatically monitor the extent of corrosion in various structures is disclosed. The corrosion sensor includes a first part made substantially similar in material construction to a structure, corrosion on which is to be sensed by the corrosion sensor, and a second part made of a corrosion-resistant material, the first and second parts being separated by a medium, thereby forming a capacitor. The capacitor configured such that change in the capacitance provides a measure of corrosion occurring in the structure.Type: ApplicationFiled: February 12, 2014Publication date: September 3, 2015Applicant: PURDUE RESEARCH FOUNDATIONInventors: Dong Chen, S.C.
