ECoG 128-Channel Grid
Polyimide substrate that follows the cortical surface — epidural or subdural, 4 to 256 sites
A thin polyimide film that lies on the cortical surface and follows its curvature and movement, carrying mid-sized sites that trade local detail for signal, on a long cable for routing to the connector. Among the 56 grid designs in the design space it is in the upper quartile: 128 sites (96th percentile), a 12 mm site-array span (82nd percentile), 0.94 sites/mm² (46th percentile) and a 74 mm³ neural interface (86th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 1 of them microdrive-compatible. Polyimide 12 µm thick. 60 mm cable. Research use only.
