Paper Abstract

High-temperature experiments for electroless Cu-plating Fiber Bragg Grating (FBG) indicate that Cu-plating FBG can measure high-temperature up to (even beyond) 300°C and it has high linearity, accuracy and repeatability. We can control Cu-plating FBG’s temperature sensitivity by controlling plating layer’s thickness. Temperature sensitivity of FBG with Cu-plating can be improved by more than three times with no less than 300μmthick coating by electroless and electrical Cu-plating. Such FBG can be soldered onto metal structures to get good bonding with the structure. As a result, such fiber sensors can get good protection, and high-temperature monitoring of smart structure is obtained.
