Impedance of electrolytes using microelectrodes coplanar

Prado, J., Margo, C., Kouider, M., Nadi, M.

A measurement cell with different sizes of coplanar electrodes was developed for measurement of electrolyte impedance. A comparative analysis has been simulated with the finite elements method (FEMLAB) and experimental study using an impedance analyzer confirmed the theoretical results. This paper presents experimental observation of polarization impedance related to the metal electrolyte interface. 100Hz to 1MHz frequency range scanned according to the limits of the analyzer.
