The article considers an analytical approach for determining the impedance of an electrochemical cell with planar interdigitated microelectrodes located in a microchannel and for estimation of the effect on the impedance characteristics of the microchannel height. The proposed approach is based on the use of an electric equivalent circuit of the electrochemical cell for determining its impedance and a mathematical simulation of the distribution of the electrical potential in the structure of interdigital microelectrodes located in a microchannel to determine the constant electrochemical cell. Using this approach, the analysis of impedance dependencies is performed and the frequency dependences of the real and imaginary parts, the modulus and the argument of the impedance of the electrochemical cell with the specific geometry of the interdigital microelectrodes for different microchannel heights are determined.
