In vivo failures common in today’s heterogeneously integrated silicon-based neural probes. The Utah intracortical electrode array (Blackrock). (a) Side view of an electrode with a large longitudinal crack in the parylene-C insulation adjacent to surface irregularities (20 µm scale). (b) Explanted UIEA array at 10 months. The array was completely encapsulated. Reproduced with permission from Bernardin ©2018 [50].
