ECoG 4-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 large sites that average a broad patch at low impedance, on a long cable for routing to the connector. Among the 56 grid designs in the design space it is in the lower quartile: 4 sites (4th percentile), a 0.5 mm site-array span (7th percentile), 0.84 sites/mm² (45th percentile) and a 5 mm³ neural interface (25th percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 2 of them microdrive-compatible. Polyimide 12 µm thick. 40 mm cable. Research use only.
