Abstract: Disclosed here are two approaches for implementing neural probes that consist of a thin, high-density Parylene C-based probe on a stainless steel shuttle. In a first approach, the high density Parylene C probe is microfabricated separately and is then affixed to a planar or curved stainless steel shuttle. In a second approach, the high-density probe is monolithically fabricated on a stainless steel shuttle by micromachining the stainless steel substrate.
