Fiber Bragg Gratings Embedded in 3D-Printed Scaffolds

In recent years there has been considerable interest in utilizing fiber optic based sensors as embedded sensor for fabricating smart materials. One of the primary motivations is to provide real-time information on the structural health of the material so as to enable proactive actions that prevent catastrophic failure. In this preliminary study we have examined the impact of surrounding matrix on the temperature dependent response of fiber Bragg gratings (FBG). Our results indicate that the surrounding matrix has a significant impact on the sensor’s temperature response suggesting quantitative use of embedded sensors will likely require the development of in corpus calibration procedures.
