1. An implantable medical electrode, comprising:

  • an electrode substrate roughened using a mechanical, non-chemical technique,an adhesion layer covering at least a portion of the mechanically-roughened electrode substrate, andan outer valve metal oxide coating comprising ruthenium oxide covering the adhesion layer to minimize post-pulse polarization voltage of the electrode,the adhesion layer preventing delamination of the outer valve metal oxide coating during application of an electrical load.
