Epicardial 64-Channel Array
Polyimide that holds contact through a beating cycle — motion artifact, not amplitude, is the limit
A thin polyimide film that lies on the epicardium and deforms with every beat, 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: 64 sites (a common choice — 9 of 55), a 29 mm site-array span (95th percentile), 0.08 sites/mm² (5th percentile) and a 423 mm³ neural interface (98th percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 150 mm cable. Research use only.
