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 small sites that read a local patch at high impedance, on a short cable for a compact head end. Among the 56 grid designs in the design space it is in the lower quartile: 32 sites (a common choice — 16 of 55), a 2.15 mm site-array span (23rd percentile), 16 sites/mm² (84th percentile) and a 1.92 mm³ neural interface (12th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 20 mm cable. Research use only.
