The main steps of studying of embedded optical fiber smart metal structure are introduced, which are metal coating for protecting the optical fiber sensors, analysis of the physical characteristics of the sensors after being metalized and embedded, and the choices of embedded metal. An electroless-electroplating method is used to protect the optical fiber for less thermal stress, which can be minimized by proper coat thickness, Young′s modulus, Poisson ratio and thermal expansion. Experiments show that the metal coats can protect the optical fiber and make the optical fiber weldable. The optical fiber sensors present good sensitivity characteristics after being metalized and embedded. However, the fiber Bragg gratings are used in most research, and their bad thermal stability makes only few methods and few host metals used in embedding the optical fiber sensors. It is believed that research of the better optical fiber sensors which can endure rugged environment when it is embedded in metal is the key problem for the study.
