ECoG 120-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 sits at the top: 120 sites (88th percentile), a 79 mm site-array span (100th percentile), 0.3 sites/mm² (27th percentile) and a 219 mm³ neural interface (93rd percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 1 of them microdrive-compatible. Polyimide 12 µm thick. 100 mm cable. Research use only.
