$TiO_2$ films are fabricated using silk printing method. Heat treatment temperature of films is 600[$^{circ}C$]. From the analysis of microstructure, grain size of $TiO_2$ films is about $0.2{sim}0.3[{mu}m]$. Thickness of films is 30.19[${mu}m$] and surface uniformity of films is good. From the analysis of crystalline structure, $TiO_2$ films transform anatase phase to rutile phase. Capacitance of films increases according to increase relative humidity and decrease measuring frequency. Hysteresis characteristics of capacitance and impedance are best at 45[%RH] and 75[%RH] respectively. Impedance of films increases according to decrease measuring frequency.
