[Distribution of current density over the surface of electrodes of an autonomic stimulator of the gastrointestinal tract].

The paper outlines a distributed self-contained gastrointestinal electrostimulator model that considers current distribution in the electrolytic environment and electrochemical polarization inhomogeneity over the surface of cap electrodes. The model is satisfactory in describing the experimental data obtained for electrodes made of the stainless steel 12X18H9 in 1% hydrochloric acid solution (that mimics gastric acid) and may be useful in evaluating the performance of and in optimizing the self-contained electrostimulator with the electrodes covered by different materials.
