Abstract
To utilize the evanescent wave on a plastic optical fiber (POF), a humidity sensor was fabricated based on a tapered POF with a loop shape and coated with zinc oxide (ZnO) nanorods. The POF was tapered manually to a diameter of 0.90 mm by using the polishing method. ZnO nanorods were synthesized using the hydrothermal method. The obtained results revealed that the increase in the length of the tapered POF loop coated with ZnO nanorod had provided an excellent sensing performance as an RH sensor in terms of sensitivity and repeatability properties. © 2022 Wydawnictwo SIGMA-NOT.
