Abstract Scope |
Long-term implantable neural interfacing devices are essential for treating neurological disorders. These devices rely on electrodes and microelectrode arrays, whose invasiveness increases potential benefits and risks. To mitigate risks and enhance performance, electrodes must be thin, flexible, and have small contacts. However, this reduces their geometric surface area and electrochemical performance. This work examines the use of femtosecond laser hierarchical surface restructuring (HSR™) to improve electrochemical performance without compromising the integrity of ultra-thin (<25µm) Pt10Ir electrodes. We developed a process that enhances the electrochemical performance of 20µm thick Pt10Ir electrodes. Comprehensive characterization assessed surface, morphological, microstructural, and electrochemical properties, aiming to identify features that promote efficient electron transfer, high electrochemical surface area, and biocompatibility. |
