Contents 1. Introduction
The combination of fiber optics with nano-structure technologies offers great potential for the realization of novel sensor concepts. Minitured optical fiber sensors with thin films as sensitive elements could open new fields for optical fiber sensor applications. Thin films work as sensitive elements and transducer to get response and feedback from environments, optical fiber here are employed to signal carrier. In this article, we review some research work of optical fiber sensors with sensitive thin films developed at the National Engineering Laboratory for Fiber Optic Sensing Technology, Wuhan University of Technology.
