well as feed-through hermeticity.

Platinum, iridium and alloys of the two will continue to play a significant role in biomedical devices due to their biocompatibility, resistance to corrosion, and electrochemical properties under physiological conditions. Processing challenges for these metals will continue to drive research and development to discover novel and efficient ways to create structures and components that meet technological demands. Namely, simpler and more reliable ways to

Hermetical packaging for implantable microelectronics will continue to use platinum and iridium feed-throughs embedded in non-reactive, electrically insulating templates/substrates. As the size of microelectronic devices decreases, and the number of feed-throughs per unit area of package increases, novel approaches to fabricating feedthrough technologies in an

Here we report on platinum-iridium alloy nanowires electrochemically deposited in nanopo‐ rous aluminum oxide using a template synthesis technique. We believe that series of nano‐ wires, connected in parallel, can be used substituted for single conducting elements of equivalent cross-sectional area. However a careful understanding of how solution chemistry, deposition potential, and other parameters affect nanowires composition and morphology as Artin Petrossians1 , John J.
