Abstract The independence estimation results of synchronously recorded pulse signals in distal parts of human radial arteries are presented in this paper. The study is carried out by the methods of structural-functional and simulation modeling in approximation of an equivalent planar movement of the biological object structural elements. Their elastic characteristics are taken into account using by electromechanical analogies. The correctness of the proposed mathematical model of pulse signals at transducer input is confirmed experimentally. The experimental studies are carried out using a device that represents piezoelectric and piezoresistive transducers connected in series (mechanically). The stiffness and the operating frequency range of the device are equal to 5217 ± 430 N/m and 0.04–32 Hz, respectively. Measurement results for a pulse signal of the piezoelectric transducer (pelot diameters are equal to 6 and 8 mm) and the piezoresistive force sensor show that in the range of transducer to zone surface pressing up to 2 N, the length of arteries areas, forming pulse signals, does not exceed 13 mm and is situated within zones accepted in oriental medicine.
