High density nanowire electrodes for intracortical microstimulation

Abstract

High-density electrodes with the nano feature size greatly enhance resolution and specificity during intracortical microstimulation. In this viewpoint, we fabricated and developed high-density nanowire (NW) electrodes, ~ 2.45×10 9 / cm 2 that could directly stimulate specific region of the cortex with low current amplitude in the range of 120-180 μA. The proposed nanowire electrodes will help expand the capabilities of microstimulation and extend the range of dysfunctions that can be treated using microstimulation technique. .
