A DEVICE HAVING A CORROSION DETECTION FUNCTION AND A METHOD OF MANUFACTURING THE SAME

摘要

A device (100) comprising a substrate (102) having a corrodible material, a grating (104) formed on and/or in the substrate (102), an electromagnetic radiation source (106) formed on and/or in the substrate (102) and adapted for directing an electromagnetic radiation beam (108) onto the grating (104), an electromagnetic radiation detector (110) formed on and/or in the substrate (102) and adapted for detecting the electromagnetic radiation beam (108) after interaction with the grating (104), and an evaluation unit (112) formed on and/or in the substrate (100) and adapted for evaluating a corrosion state of the corrodible material based on the detected electromagnetic radiation beam (108).
