Humidity sensing using microfiber-ZnO nanorods coated glass structure

In this paper, a proposed humidity sensor is fabricated by integrating the microfiber and the glass surface coated with Zinc Oxide (ZnO) nanorods. The silica fiber diameter was reduced to 6 mu m using the flame brushing technique, and the glass surface was coated with ZnO nanorods using a hydrotherm...
