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.
