Electroactive coating of stimulating electrodes
A new coating, electrolytically deposited electroactive iridium oxide, has been developed to decrease the interface's impedance. The decrease of impedance is demonstrated by impedance spectroscopy: the low-frequency limit is lowered by more than three orders of magnitude to a value of 0.4Hz. Th...

Summary: | A new coating, electrolytically deposited electroactive iridium oxide, has been developed to decrease the interface's impedance. The decrease of impedance is demonstrated by impedance spectroscopy: the low-frequency limit is lowered by more than three orders of magnitude to a value of 0.4Hz. This is due to the electroactivity of the material which is caused by reversible proton incorporation into the coating. Due to the low interface impedance well below 1 Hz, the coated electrodes fulfill the requirements for medical applications. Outstanding sensing behavior is also shown. |
