| Abstract Scope |
Next-generation neurostimulation therapies demand miniaturized, high-density electrode arrays with superior electrochemical performance, long-term stability, and biological compatibility. Hierarchical Surface Restructuring (HSR) is a femtosecond laser-based technology that engineers the surface of platinum-iridium electrodes to generate hierarchical surface architectures that drastically enhance electrochemically active surface area (ESA). This study presents a comprehensive evaluation of HSR-treated electrodes, including: (1) improvements in impedance, charge storage capacity (CSC), and specific capacitance; (2) integration of CO₂-snow-assisted processing to minimize redeposition and preserve surface integrity; and (3) antibacterial functionalization via thin film coatings that provide additional bioactivity without compromising electrochemical performance. |
