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. Among the 56 grid designs in the design space it is in the upper quartile: 64 sites (a common choice — 9 of 55), a 15 mm site-array span (89th percentile), 0.3 sites/mm² (25th percentile) and a 114 mm³ neural interface (89th percentile).
Orders as a grid-plus-package assembly, in 5 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. Research use only.
