    Interface Impedance and Cell Constant Corrections of Planar Comb-like Electrodes

  • Original language description

    Planar comb-like electrodes called also interdigitated electrodes (IDEs) are used as miniature and cheap chemical sensor for widespread use as conductivity-based transducer. The thick-film Pt planar sensor has been characterised by a precise impedance analyser over a wide range of frequencies and conductivities. The frequency characteristics have been studied to describe the electrode behaviour, and for comparison with theory. We found relations between conductivity and frequency. The ridge frequency waas detected as suitable measuring frequency to improve accuracy. Extracted relations can be used as correction characteristics. The correction factor was determined for wide range of conductivity to take precise measurements without cell replacement.

  • Czech description

    Planární hřebínkové elektrody dále nazývané jako Interdigitated elektrody (IDEs) jsou využity jako miniaturní a levné chemické senzory pro široké využití jako měnič založený na vodivosti. Tlustovrstvý Pt planární senzor byl charakterizován přesným impedančním analyzátorem pro širokou škálů frekvencí a vodivosti. Kvůli popisu chování elektrody byly frekvenční charakteristiky byly studovány a srovnány s teorií. Našli jsme vztah mezi vodivostí a frekvencí.
