Measurements of Strain

2.8K
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:

    • Fiber optic sensing
    • Interferometry
    • Strain measurement

    Background:

    • Fiber optic sensors offer remote and precise measurement capabilities.
    • Fabry-Perot interferometers (FPI) are widely used for sensing applications.
    • Standard single-mode fibers are readily available and cost-effective.

    Purpose of the Study:

    • To develop a high-sensitivity strain sensor.
    • To enhance the sensitivity of an in-fiber FPI strain sensor.
    • To minimize temperature cross-sensitivity in strain measurements.

    Main Methods:

    • Fabrication of an in-fiber FPI with an air cavity by splicing standard single-mode fibers.
    • Enhancement of the FPI cavity length using repeated arc discharges for reshaping.
    • Characterization of strain and temperature sensitivity.

    Main Results:

    • Achieved a high strain sensitivity of 6.0 pm/με.
    • Demonstrated a low temperature sensitivity of 1.1 pm/°C.
    • Successfully reduced cross-sensitivity between strain and temperature.

    Conclusions:

    • The developed in-fiber FPI strain sensor exhibits high sensitivity and low temperature dependency.
    • The method of reshaping the air cavity is effective for enhancing sensor performance.
    • This sensor is suitable for applications requiring accurate strain monitoring with reduced environmental interference.
