EEG 32-Channel Grid
Recorded from outside the skull, no craniotomy — resolution traded for a preparation that lasts months
A thin polyimide film that sits on the outside of the skull, with no bone removed and no dura opened, carrying large sites that average a broad patch at low impedance. Among the 56 grid designs in the design space it is mid-range: 32 sites (a common choice — 16 of 55), a 6.5 mm site-array span (54th percentile), 0.62 sites/mm² (41st percentile) and a 30 mm³ neural interface (59th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. Research use only.
