    Abstract:

    A novel sensor using twisted optical fibers is proposed to detect distributed tensile strain. This sensor converts tensile strain to optical loss. The relation between tensile strain and optical loss is modeled and experimentally confirmed for uniform tensile strain.

    Design Example: Strain Gauge Bridge or Wheatstone Bridge

    The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...
