Thin-Film Lead Assemblies And Neural Interfaces

A thin-film neural interface comprising:

• a supporting structure comprised of one or more layers of dielectric material, wherein the supporting structure comprises a front side, a back side, and opposing edges;
• one or more conductive traces formed on the one or more layers of dielectric material;
• one or more electrodes formed on the front side of the supporting structure in electrical connection with the one or more conductive traces;
• and
• a backing formed on the back side of the supporting structure and wraps around the opposing edges from the back side of the supporting structure,
• wherein the backing is comprised of a medical grade polymer material, the opposing edges comprise a pattern in the one or more layers of dielectric material, and the backing further comprises a pattern in the medical grade polymer material that interlocks with the pattern in the one or more layers of dielectric material.
