Abstract :
In this study, sputtered iridium oxide films were subjected to a long-term stimulation and accelerated soak procedure to determine the ability of these electrodes to maintain high level of charge injection in an in vitro environment without delaminating. Scanning electron microscopy was used after the procedure to examine the electrodes for delamination. Characterization of the electrochemical properties of reactively sputtered iridium oxide films on LCP was also performed.
