ECoG 32-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. Among the 56 grid designs in the design space it is mid-range: 32 sites (a common choice — 16 of 55), a 3.2 mm site-array span (38th percentile), 1.39 sites/mm² (54th percentile) and a 14 mm³ neural interface (54th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. Research use only.
