Precision Electrode System for Electrical Impedance Myography

Currently, commonly used methods of control, in particular, based on electromyogram signals, do not allow to get detailed information about biomechanical characteristics of muscle activity. As a result, it is not possible to determine the type of movement of the limb segment and its force-moment parameters. An urgent task is to study new methods of anthropomorphic bionic control based on measured data of the electrical and biomechanical activity of muscles and muscle groups, in particular, electrical impedance myography, which will form proportional degrees of muscle contraction. The design of the electrode assembly is proposed for studying the mechanisms of generating electrical impedance myography signals, which is one of the new ways to implement anthropomorphic bionic control. Measuring the EIM signal requires the development of a special electrode system that will meet the following requirements: without the mutual effect of the electrodes due to their finite size, minimize polarization effects, the maximum possible number of combinations of electrode systems with a limited number of electrodes.
