Iridium Oxide as A Stimulating Neural Electrode Formed By Reactive Magnetron Sputtering

摘要

Implantable neural prostheses form hybrid interfaces with biological constructs, and the application of electrical fields can restore functions of patients with neurological damages. The various stoichiometric compositions of iridium oxide were synthesized using reactive magnetron sputtering. The charge injection behavior of iridium oxide deposited with an O_2/Ar ratio of 0.5 was similar to pure Ir. The charge density of iridium oxide increased with increasing O_2/Ar ratio, and increasing thickness of iridium oxide.
