Relative humidity sensor employing optical fibers coated with ZnO nanostructures
We demonstrate two simple relative humidity sensors using a tapered Plastic Optical Fiber (POF) and silica microfiber. The POF is tapered by chemical etching method whereby the fiber is immersed into acetone and polished by a sand paper to reduce the fiber’s waist diameter from 1 mm to about 0.4 -...

| description | We demonstrate two simple relative humidity sensors using a tapered Plastic Optical Fiber (POF) and silica microfiber.
The POF is tapered by chemical etching method whereby the fiber is immersed into acetone and polished by a sand paper
to reduce the fiber’s waist diameter from 1 mm to about 0.4 - 0.5 mm. The silica microfibers were fabricated using flame
brushing techniques. Both tapered fibers are then coated with zinc oxide (ZnO) nanostructures using sol-gel immersion
on ZnO seeded and non-seeded fiber methods before it is used to sense relative humidity. It is found that the tapered POF
coated with seeded ZnO performed better compared to tapered silica microfiber. The tapered POF coated with seeded ZnO
based sensor has linearity and sensitivity of 94.41 % and 0.176 mV/%, respectively. |
