ECoG 256-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 long cable for routing to the connector. Among the 56 grid designs in the design space it is mid-range: 256 sites (100th percentile), a 3.08 mm site-array span (34th percentile), 27 sites/mm² (89th percentile) and a 6.41 mm³ neural interface (30th percentile).
Orders as a grid-plus-package assembly, in 2 package configurations. Polyimide 12 µm thick. 30 mm cable. Research use only.
