ECoG 128-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 mid-range: 128 sites (96th percentile), a 1.44 mm site-array span (14th percentile), 29 sites/mm² (91st percentile) and a 3.43 mm³ neural interface (21st percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 1 of them microdrive-compatible. Polyimide 12 µm thick. 8 mm cable. Research use only.
