Abstract
The present disclosure relates to neuromodulation electrodes, and in particular, to neuromodulation electrodes having a platinum/iridium surface etched with a pattern and methods of laser etching the pattern into the platinum/iridium surface of the neuromodulation electrodes to improve performance of the neuromodulation electrodes. Particularly, aspects are directed to an electrode including a base body having: (i) an interface surface that has an area of less than 50 mm2, and (ii) an alloy including platinum and iridium. The interface surface has a surface topography including: (i) an artificial pattern, and (ii) a surface roughness having an arithmetical mean height (Ra) of greater than 0.8 μm.
