Abstract:Optical hydrogen sensors can use optical fiber as the medium for light transmission or sensing, and realize hydrogen detection based on the relevant physicochemical properties of hydrogen-sensitive materials, which have excellent characteristics such as intrinsic safety, good stability, small size, high specificity, and easy to network. However, traditional hydrogen-sensitive materials such as Pd metal usually require a large thickness to obtain good performance, but this will shorten the service life of the s… Show more
