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 stimulating electrodes. It is shown that, if adequate growing conditions 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 reversible way, therefore without generating new products to the solution.This paper was accepted for publication after the 1995 Conference of the European Society of Biomaterials.
