| Popis: | Electrochemical hygrometers have been fabricated using orange dye (OD) C17H17N5O2 thin films, deposited from aqueous solution under normal conditions. The films were deposited on zinc substrates from 10 wt.% solution of OD in distilled water. These films were than used to make samples of Zn/OD-TP/Cu, Zn/OD/Cu and Zn/OD/Graphite (TP stands for tissue paper); copper electrode was used in the form of a mesh and the graphite in the form of a porous solid. Properties of the samples were investigated in a range of 46-78% humidity. Output voltage and current of the sensors were monitored in electrochemical mode of operation, showing a rise of 8 and 100 times, respectively, with an increase in humidity. These electrochemical hygrometers may be potentially useful for developing humidity meters. |
