| Abstract |
CaTiO_3 thin films using silk screen printing technology were fabricated and their humidity sensitive characteristics have been investigated. The specimens were sintered at 1000^{\circ}C, 1050^{\circ}C, 1100^{\circ}C for 1 hour and the best humidity sensitivity was shown in the specimens sintered at 1000^{\circ}C. The humidity sensitivity decreased with increasing measuring frequencies and was stable at different abient temperatures. Hysteresis of impedance variation with increasing and decreasing relative humidity were negligible. |
