Original Abstract

This paper describes a problem of unknown electrochemical behavior of different topologies of thick-film electrochemical sensors. Using DC voltammetry, there were examined the properties of working and reference electrode by output current response and peak potential in this paper. Several electrodes containing different size of electrode area made of Ag, Au and Pt were prepared for this purpose. The influence of working electrode area size of common electrochemical sensor to output current response was measured against commercial Ag/AgCl reference and Pt auxiliary electrode. As we supposed, the results confirm the Levic equation for solid electrodes. The influence of reference electrode area size of common electrochemical sensor to output current response and peak potential was measured against commercial Au working and Pt auxiliary electrode. The results confirmed presumption that for small sized thick-film sensors, the three-electrode arrangement is more accurate and reproducible than two-electrode system.
