Abstract

A method and an electrochemical sensor device for determining a fatigue status of a growing crack in a substrate. The device includes an electrode formed from a stainless steel mesh and having a bottom surface that is coated with an adhesive layer and has a release paper attached to the adhesive layer. The adhesive layer is exposed through separation of the release paper from the adhesive layer. Contacting the adhesive layer to the substrate secures the device to the substrate and forms a cavity that contains an electrolyte and is partially bound by the substrate. The adhesive seals the bottom surface of the device to the substrate in order to prevent leakage of electrolyte from the cavity. When the substrate is subjected to cyclic loading, the fatigue status of the growing crack in the substrate is determined in accordance with a measured current between the reference electrode and the substrate.
