Epicardial 128-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: 128 sites (96th percentile), a 15 mm site-array span (89th percentile), 0.29 sites/mm² (21st percentile) and a 234 mm³ neural interface (95th percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 1 of them microdrive-compatible. Polyimide 12 µm thick. 150 mm cable. Research use only.
