Electroactive coating of stimulating electrodes

Surface Plasmon Resonance in Novel Nanocomposite Gold/Lead Zirconate Titanate Films Prepared by Aerosol Deposition Method

“…The curves are nearly symmetrical along the potential axis indicating excellent electrochemical reversibility and equal anodic and cathodic charges transferred through the electrodeelectrolyte interface. In each of these curves, current peaks due to redox reactions can be distinguished [17]. However, their sizes, shapes, and positions vary slightly between the samples.…”

Large charge-storage-capacity iridium/ruthenium oxide coatings as promising material for neural stimulating electrodes

“…However, due to its low charge injection, softness and dissolution at lower charge density limit its wide spread use [2,8,16,17]. Similarly, other well-known electrode materials like silveresilver chloride and stainless steel also dissolve when come in contact with the biological tissues thus, causing inflammation [10,14]. Other nobel metals such as pure ruthenium and rhodium have also been investigated as neural electrodes, but these electrodes have certain problems such as low biocompatibility and high cost [18e21].…”

“…Several metal-based electrode materials have been developed and tested for neural stimulation; titanium, tantalum, titanium nitride, stainless steel, platinum and Pt alloys, iridium, ruthenium and rhodium [2,8,14]. Platinum is the most prominent neural stimulation electrode material used in prosthetic devices due to its relatively high biocompatibility [12,15].…”

Influence of the annealing treatment on the structure, morphology, and corrosion resistance of sputtered Zr‐Ti‐Si‐O coatings used for biomedical applications

“…Metallic oxides are potential candidates as implantable biomaterials due to their remarkable properties such as chemical stability, high corrosion resistance which involves a low corrosion rate and bioactive properties [3]. Also, they cause a low degree of inflammation after the release of corrosion products during the electrochemical process [4][5][6][7][8][9][10][11][12]. Among them, titania coatings have been studied intensively due to their high refractive indices, hardness, durability, low absorption, etc.…”

“…Among them, titania coatings have been studied intensively due to their high refractive indices, hardness, durability, low absorption, etc. [4][5][6]13]. Zirconia is also well suited for biomedical use, especially total hip replacement, due to its high mechanical strength and fracture toughness [14].…”
