Intensity modulation induced by microbending in multimode fibers is considered as a transduction mechanism for detecting environmental changes such as displacement and pressure. The relevant microbend sensor components such as sensing fiber, light source, leads, and detector have been examined and optimized. Finally, the micro-bend sensor has been tested as a displacement sensor demonstrating good performance.
