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. It's a device that converts light rays into electronic signals. Think of it like a photoresistor, which changes its resistance based. This paper conducts a systematic analysis of the sensing mechanisms in fiber-optic pressure sensors, with a particular focus on the performance optimization effects of fiber structures and materials, while elucidating their application characteristics in different sensing scenarios. It aims to provide a comprehensive collection of cutting-edge research that pushes the boundaries of fiber optic sensor technologies, integrating them with emerging trends and. Fiber-optic sensors (also called optical fiber sensors) are fiber -based optical sensors for some quantity, typically temperature or mechanical strain, but sometimes also displacements, vibrations, pressure, acceleration, rotations (measured with optical gyroscopes based on the Sagnac effect), or. These advantages are essentially related to the optical fiber properties, i.
