ECoG 29-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 in the lower quartile: 29 sites (34th percentile), a 0.34 mm site-array span (4th percentile), 134 sites/mm² (98th percentile) and a 0.48 mm³ neural interface (5th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 25 mm cable. Research use only.
