Electrochemical properties of platinum, glassy carbon, and pyrographite as stimulating electrodes.
Presently, platinum, platinum-iridium, and carbon (glossy and pyrographite) are the preferred materials to be used as stimulating electrodes. Electrochemical tests revealed higher thresholds with Pt-Ir, which possibly are a result of excessive connective tissue growth. A porous structure appears to be preferred especially if the electrode materials are smooth and activated glassy carbon. When comparing power consumption, glassy carbon was found to be a superior electrode material.
