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 -...
