| Abstract: | Humidity sensors are widely used in domestic and industrial environments. The authors have investigated 0.5ZrO2–0.5TiO2
ceramic for its humidity sensing electrical properties at room temperature. The bulk humidity sensors were prepared by the
conventional ceramic method. Salt doping with Li+ ions is found to increase the sensitivity by an order of two, and also improves the linearity. X-ray and scanning electron microscopy (SEM) investigations have established that ZrTiO4 phase grows at a sintering temperature of 1200°C. The abnormal behaviour in humidity sensing characteristics for samples sintered at 1150°C may be due to micropores in between the grains. |
