Fiber optic strain sensors operate based on the strain-optic effect, where mechanical deformation of an optical fiber alters its physical dimensions and refractive index, causing measurable changes in the light traveling through it . These changes can manifest as shifts in wavelength, intensity, phase, or polarization, which are then translated into precise strain measurements. Unlike traditional strain gauges, fiber optic sensors are non-intrusive, resistant to harsh environments, and immune to electrical hazards .
Fiber optic strain sensors are widely used in:
Fiber optic strain sensors provide a highly accurate, durable, and versatile solution for measuring strain in various environments. Their ability to operate in harsh conditions, combined with multiplexing and distributed sensing capabilities, makes them superior to traditional strain gauges for modern structural and industrial monitoring applications .
Therefore, new methods need to be developed further for economic high-sensitivity strain sensors. In this paper, an ultrasensitive
