As a sensing technology based on the principles of optical fiber, fiber optic sensors have gradually become key equipment in many industries due to their advantages, such as high precision, strong anti-interference, and long transmission distances. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. , small, lightweight, resistant to high temperatures and pressure, electromagnetically passive, among others. The fiber optic sensor has an optical fiber connected to a light source to allow for detection in tight spaces or where a small profile is beneficial. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.

These sensors use light signals to detect physical parameters such as temperature, pressure, strain, and vibration. The performance of fiber optic sensors can be evaluated based on several key factors including sensitivity, accuracy, resolution, linearity, hysteresis . Although the IEEE-SA Industry Connections activity members who have created this Work believe that the information and guidance given in this Work serve as an enhancement to users, all persons must rely upon their own skill and judgment when making use of it. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of.

This review offers a comprehensive analysis of recent advances in optical fiber-based pH sensors, covering key techniques such as fluorescence-based, absorbance-based, evanescent wave, and interferometric methods. Innovations in Fiber Bragg Grating and Surface Plasmon Resonance technologies are. While pH determination is a commonplace laboratory practice, conventional commercial pH probes exhibit drawbacks of bulkiness, slow response times, and signal drift. These become particularly limiting in specialized fields like tissue engineering and bio-industrial processing, where unique pH probe. Background: This study presents the development and characterisation of an optical fibre coated with silver nanoparticles and silica composite for pH measurement, where pH corresponds to the negative log of hydrogen ions in solution.
