Measurements of Strain

2.5K
Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain...

    Area of Science:

    • Optical Engineering
    • Fiber Optic Sensors
    • Materials Science

    Background:

    • Fiber Mach-Zehnder interferometer (MZI) sensors are crucial for strain measurement but face limitations in sensitivity due to refractive index variations.
    • Existing MZI strain sensors cannot be further improved in sensitivity based on the refractive index difference between fiber core and cladding.

    Purpose of the Study:

    • To propose and experimentally validate a high-sensitivity fiber strain sensor using a circular ring structure.
    • To overcome the sensitivity limitations of conventional MZI strain sensors.

    Main Methods:

    • A single-mode fiber was bent into a circular ring, with the intersecting part fixed spirally.
    • Axial strain applied to the fiber caused the circular ring to deform into an ellipse, altering mode coupling and sensing area length.

    Main Results:

    • The circular ring structure MZI demonstrated a high strain sensitivity of 91.55 pm/με.
    • The sensor achieved a reliable strain detection range of 0-400 με.

    Conclusions:

    • A novel approach for strain sensitization in MZI sensors was developed by modifying the sensing area length.
    • The proposed sensor offers significantly increased sensitivity, suitable for demanding applications like aerospace engineering.
