Regression equations of connection intracellular fluid of biological object with them electrical characteristics
Abstract
Bioimpedance measurements of biological objects were made. Using the capacitive and active resistance of the human body at frequencies of 5 and 50 kHz, the active resistances of the within and extracellular fluids, as well as the total capacity of the total cell mass, were experimentally determined. Based on electrical characteristics obtained by bioimpedance method, the intracellular fluid of biological objects is analyzed. The regression equation of the connection between the mass of the intracellular fluid and the electrical parameters of the biological object is compiled: the active resistance of the liquid fraction and the capacitive characteristics of the cell mass membranes.
