摘要：

The development of a highly sensitive optical fiber humidity sensor for Relative humidity measurement (RH) is described in this article. For the development of the sensor, an rGO-TiO2 nanocomposite doped thin silica film was deposited over the centrally de-cladded region of a plastic cladding silica (PCS) fiber. In order to get the sensor response, a rigorous experimental investigation was carried out. A linear response from 3% to 70%RH with sensitivity 0.01RH(-1) (59.1mV/%RH) is observed for the developed sensor. The sensor exhibits an average response and recovery time of 3s & 2.5s, respectively, with a high degree of repeatability.
