Distributed sensing, based on Rayleigh scattering or arrays of reflectors, can be extended as a multi-fiber, multi-sensor technique by using multiplexing features. Current research has overcome the time-and wavelength-division multiplexing, that has represented the golden standard for fiber Bragg gratings. In this work, we introduce novel...

This paper presents the development and implementation of an-optical fiber integrated smart environment with heterogeneous opto-electronic approaches. In this case, the so-called Opto-electronic Smart Home is composed of three different optical fiber sensor system, which are also based on different optical fibers, resulting in more than 50...

High-scattering optical fibers have emerged as a key component in distributed sensing systems, primarily due to their capacity to enhance signal-to-noise ratio. This paper presents an experimental characterization of optical fibers doped with oxide nanoparticles for displacement sensing. They were manufactured using the phase-separation...

This article presents the development of a nanoparticles (NPs)-doped smart tendon for 3-D shape reconstruction applications. The proposed smart composite structure is based on the combination of NP-doped optical fibers immersed into a polyurethane (PU) matrix with a silicone cover. In the proposed NP-doped optical fiber, the interaction between...

We present results for the disturbance location characterization of Transmission-Reflection Analysis (TRA)-based sensors using three different optical fibers doped with dielectric nanoparticles (DNP). Different DNPs ( SrO , CaO and MgO ) lead to different sensors' performance due to the composition-dependent properties. Fibers doped with bigger...
