Optical fibre sensors are an essential subset of optical technology, designed specifically for sensing and measuring several physical parameters. These offer unique advantages over traditional sensors, making them gradually more valuable in a wide range applications. They can detect extremely small variations the parameters they to measure, such as analytes case biosensing. This high sensitivity allows subtle temperature, pressure, strain, refractive index analytes, vibration, other environmental factors with exceptional accuracy. Moreover, these enable remote capabilities. Since light signals used carry information, elements be placed at distant or inaccessible sites still communicate data back central monitoring system without signal degradation. In recent times, different attractive configurations approaches have been proposed enhance fibre-based sensor briefly explained this review. However, we believe that choice configuration should designated based on specific application. As continue evolve improve, will play increasingly vital role critical control applications across various industries.

Fiber optic sensors have gained popularity over the last few decades. This is due to their numerous advantages, such as good metrological parameters, biocompatibility and resistance magnetic electric fields environmental pollution. However, those built from glass fiber one main disadvantage—they are fragile, meaning they can be easily damaged, even by presence of vibration. Due great progress made material research recently, it possible build a sensor with polymer fibers instead. Although worse transmission parameters compared telecommunication fibers, provide possibility realize flexible sensors. Taking into consideration other advantages including biocompatibility, electromagnetic even, biodegradation characteristics, well there being variety materials we use, seen that beneficial produce paper aims researchers guidelines on factors consider when choosing for bent sensors, depending application.
