Treatment of diseases associated with the nerve fibers conductivity disorder, as well as the analysis of the status of injured or recovered by surgical intervention fibers require the necessity of registering the variables biopotentials of the nerves and muscles of living organisms. In addition, the recording device should have a relatively small size comparable to the fibers diameter and be directly interfaced with the control object. The direct interface with the object under control should ensure the possibility of active control of the object activity by means of an external electrical excitation signal.

To solve these problems, a prototype of the inductive sensor (an analogue to the “Rogowski’s belt") has been developed, representing a solenoid deformed twice with respect to the symmetry axis and having the dimensions adequate to the fiber under test. The developed sensor has passed preliminary tests in the laboratory of experimental neurosurgery SarNIITO. The possibility of the active application of external excitation pulse signal is currently supposed to be investigated. As for electrical parameters, the sensor is compatible with the electromyographer produced by KEYNOING company that allows for an informative use of its operational capabilities.
