Veins in biological tissue produce electrical impedance to the alternating current passes through it. Bio-impedance method based on measuring this electrical impedance value using an array of surface electrodes has the capability of detecting peripheral veins. This paper presents the theoretical and experimental studies, reflecting the possibility of impedance method of peripheral veins localization. Mathematical model has been proposed to calculate the resistivity anomalies of vein in soft tissues and reflects the electrical impedance characteristic, depending on the location of the electrode system and the vein. A system electrode has been designed to be attached to the body in order to measure the electrical impedance value. The data obtained will determine the capabilities of the method. Experimental studies confirm the adequacy of the proposed mathematical model.
