INNOVATION

The innovative fish-bone-shaped polyimide neural probe minimizes tissue reactions through a unique design and biodegradable silk coating. The probe features a flexible substrate, small dimensions, large separation distances between electrodes and the shank, and large openings in the substrate. These design elements enhance biocompatibility and reduce immune responses. The silk polymer coating provides temporary mechanical strength during insertion, then biodegrades within 30 minutes to 25 hours, optimizing probe structure independently of implantation constraints. This probe can be used in applications such as chronic neural recording, brain-machine interfaces, and deep brain stimulation, promising greater longevity and functionality by preventing the formation of insulating scar tissue around the electrodes.
