Abstract: In recent years there has been considerable interest in utilizing embedded fiber optic based sensors for fabricating smart materials. One of the primary motivations is to provide real-time information on the structural integrity of the material so as to enable proactive actions that prevent catastrophic failure. In this preliminary study we have examined the impact of embedding on the temperature-dependent response of fiber Bragg gratings (FBG). Our results indicate that scaffold… 

Fiber Bragg gratings embedded in 3D-printed patches for sensitivity enhancement of deformation monitoring

It is shown that the patch thickness, by increasing the distance between the optical sensor and the neutral axis of the structure where it is fixed, provides a gain factor in the device sensitivity to deformation.

Study of Fiber Bragg Gratings Embedded in 3D-Printed Patches for Deformation Monitoring

Aim of this work is the analysis of the 3D printed patches embedding fiber Bragg gratings (FBGs) for deformation monitoring. In particular, the paper first describes the manufacturing process and the

Design, Fabrication and Testing of a 3D Printed FBG Pressure Sensor

It is found that the FBG sensor can be successfully embedded into PLA material without sacrificing its sensing performance and the change of infill density has no influence on both peak and residual wavelength change of FBG sensors during and after the printing process.
