The European FP7 project “SmartFiber” is developing the world first full embedded optical “Structural Health Monitoring” (SHM) system for composite materials. This optical sensor system is designed to be embedded into carbon or glass fiber material for continuous monitoring of its mechanical properties. This paper presents the project goals and technologies and gives detailed information about the wireless data and energy transmission between the embedded module (interrogator) and the external read out unit. The aim of the Smart-Fiber project is to develop a system that can be embedded as one small unit containing sensor and data preprocessing, enabling the structural monitoring of the fiber material without disturbing its structure.
To reach this goal seven partners join their forces to combine the needed key-technologies like nanophotonics, advanced Fiber Bragg sensors (FBGs), automatic embedding and wireless data and power transmission, optimize and miniaturize them to build a “smart composite”.
