It is inevitable challenge to investigate electrode material with low interfacial impedance and enhanced charge transfer capacity. In this study, stimulus nerve cuff electrodes on polyimide with Pt, conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT), black Pt, and IrO, were fabricated and characterized. The electrochemical properties were investigated using cyclic voltammetry, electrochemical impedance spectroscopy, and voltage transient measurements. From the experimental results, stimulus nerve cuff electrodes with black Pt showed the highest charge delivery capacity (80 times higher than Pt), charge injection capacity (6 times higher than Pt), and the lowest interfacial impedance (3.8 times lower than Pt).
