Electrochemical impedance spectroscopy applied for assessment of electrodes used in EEG examination

Abstract

The aim of this paper was to assess commercially available electrodes used in EEG examination. Electrochemical Impedance Spectroscopy was used to investigate properties of four types of electrodes in different temperatures. Special attention was paid to the usability of electrodes used for registration of slow EEG potentials. Obtained results allowed to compare examined electrodes and to form recommendation on choose of the type of electrode.
