摘要：
The MgO doped ZrO2-TiO2 ceramic composites have been prepared in the bulk pellet form by a solid-state reaction method and studied for its humidity sensing characteristics. The dc resistance of the bulk pellet shows very high sensitivity to humidity. The higher sensitivity in the lower humidity range observed for samples sintered at 1175 degreesC is due to maximum pores in the lower diameter range. The sensors respond quickly to ambient humidity variation. The response lime largely depends oil the porous structure of the pellet.
