Abstract
In this study, a pressure sensor based on an optical fiber coated with polydimethylsiloxane (PDMS) was designed and investigated. Tapered polymer optical fibers with different thicknesses were fabricated and examined. Experimental results demonstrate that increasing the applied pressure leads to a reduction in the output light intensity of the sensor. Among the tested samples, the tapered optical fiber with a thickness of 0.58 mm exhibited the highest sensitivity to applied pressure. Furthermore, the findings indicate that through optimized coating techniques and precise adjustment of the PDMS layer dimensions, a sensitivity of approximately 4.26 a.u/kPa can be achieved.
