ECoG 64-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 small sites that read a local patch at high impedance. Among the 56 grid designs in the design space it is mid-range: 64 sites (a common choice — 9 of 55), a 2.55 mm site-array span (29th percentile), 4.97 sites/mm² (70th percentile) and a 8.46 mm³ neural interface (38th percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. Research use only.
