The results of experimental investigation of the states and concentrations
of the metal ions and humidity influence on the resistance of poly-vanadium
-titanium xerogels are presented. The resistivity of thin-film samples decr
eases with an increase of humidity as an exponential function. The final re
sults indicated that vanadium-titanium xerogels are more suitable for humid
ity sensors fabrication than other investigated vanadium hydrates. (C) 1999
