Studies of the Electrochemical Properties of Thin-Film Materials for Coating Cardiac Stimulator Electrodes

Resumo

The frequency characteristics of the admittances of a series of candidate materials for coating pacemaker electrode poles were studied. A method for assessing the properties of current transfer from an electrode connected to a source of stimulatory impulses to tissues is described. The main factors influencing decreases in the effectiveness of this transfer are identified. Potential physical vapor deposition technologies for depositing coatings, followed by alloying of films with metal ion beams, which increase the production of charged particles on the surfaces of the poles, are presented.
