This article considers one of the parts of the development of a device for determining the magnetic characteristics of ferromagnetic materials with a shape memory effect. A functional diagram of the device has been developed. The operation of the device was simulated and the behavior of the shape memory alloy was studied. The error in determining the magnetic characteristics of the FMSF using the magnetizing setup of the developed device did not exceed 0.25%.

it is known that the human body consists of water, proteins, minerals and adipose tissue, the sum of which is body weight. An important condition for maintaining health is the balance of the main components found in the internal organs of a person. Currently, the development of modern technologies allows you to find out the exact composition of your body, as well as internal organs, without complicated analyzes, using special devices that are based on measuring the bioimpedance of living tissue. Absolutely all tissues can conduct electric current, while the more water in the tissues, the more electrical conductivity and less resistance., The opposite is also true. Bioimpedance analysis measures the reactance of parts of the human body at different frequencies. On the basis of which the characteristics of the composition of the body or internal organs are calculated. Meanwhile, the measurement of the impedance of a person or his internal organs is associated with certain problems. So distorting factors can be the position of a person in space, improperly prepared areas of the body from which data are taken, improper placement of electrodes, poor contact. The aim of this work was to construct a regression model of a device for measuring the impedance of a biological object (BO), reflecting the contribution of the BO impedance to the total impedance of the entire measurement section.
