Three types of wearable optical fiber sensors are analyzed: wearable optical fiber sensors based on Fiber Bragg grating, wearable optical fiber sensors based on light intensity changes, and wearable optical fiber sensors based on Fabry–Perot interferometry. They leverage modalities such as phase modulation, speckle analysis, and polarimetric. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. Think of it like a photoresistor, which changes its resistance based. birth of fiber optic sensors. These sensors are capable of measuring a wide range of physical and chemical parameters such as temperature, pressure, vibration, displacement.
