The dependence of the active and reactive impedance components of a three-element electrical circuit of substitution of a biological object on the change of the parameters of the electrode impedance is investigated.

The results of mathematical modeling of the impedance components of a multielement two-pole representing the tissues of the human body are considered. Analyzing the known methods and their implementation by electrical models showed different research results. This is due to the fact that the research uses different electrical models, different types of sensors, different frequent ranges, circuits for connecting the sensor to the measuring instrument, etc. The measurement result can be used to identify the tissue of biological objects (taking into account the area of current electrodes, its shape and contact resistance, since these factors determine the electrode impedance).
