ELECTROCHEMICAL RESPONSE OF IRIDIUM OXIDE FOR IMPLANTED NEURAL STIMULATING ELECTRODES

The electrochemical behaviour of Ir oxide films, grown in neutral PBS saline solution has been examined in relation to their use as neural s timulating electrodes. It is shown that, if adequate growing condition s are chosen, this material is suitable for use as a neural prosthesis , since it is able to pass high values of charge density in a very rev ersible way, therefore without generating new products to the solution .
