Working principle of fiber optic barometric pressure sensor
Fiber optic pressure sensors operate based on the principle of light modulation in optical fibers. When pressure is applied to the sensing element, it changes the properties of the fiber, such as the refractive index or the intensity of the light. These sensors are gaining popularity. Fiber-optic sensing (FOS) technology has emerged as a cutting-edge research focus in the sensor field due to its miniaturized structure, high sensitivity, and remarkable electromagnetic interference immunity. In the simplest case this can be a mechanical system that blocks the light as the pressure increases.

Principle of Photonic Crystal Fiber Optic Sensors
Photonic crystal fibers (PCFs) are a special class of optical fibers with a periodic arrangement of microstructured holes located in the fiber's cladding. Light confinement is achieved by means of either index-guiding, or the photonic bandgap effect in a low-index core. The different strategies successfully applied in order to obtain feasible and reliable monitoring systems in several application fields, including medicine, biology, environment.

Working Principle of Fiber Optic Microbending Sensor
Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as pressure, temperature, acceleration, and magnetic and electric fields. Fiber Optic Cable: Standard single-mode or multimode optical fibers are used. Multimode fibers are often preferred due to their higher sensitivity to bending. This can take various forms, but typically involves. Microbends are microscopic bends of an optical fiber, which can cause bend losses (bend-induced propagation losses) even when the fiber is macroscopically kept straight. Also, they influence the polarization mode dispersion. A generic microbend sensor has been defined and studied, and its components. This work proposes a highly sensitive sandwich heterostructure multimode optical fiber microbend sensor for heart rate (HR), respiratory rate (RR), and ballistocardiography (BCG) monitoring, which is fabricated by combining a sandwich heterostructure multimode fiber Mach–Zehnder interferometer. Microbending basics Microbending attenuation of an optical fiber relates to the light signal loss associated with lateral stresses along the length of the fiber.
