Nerve-Cuff 24-Channel Array
Pre-curved polyimide that wraps rather than penetrates — diameter fixed at fabrication
A thin polyimide film pre-curved to wrap a peripheral nerve from the outside, 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 is mid-range: 24 sites (32nd percentile), a 4.62 mm site-array span (48th percentile), 1.43 sites/mm² (55th percentile) and a 11 mm³ neural interface (43rd percentile).
Orders as a grid-plus-package assembly, in 6 package configurations, 3 of them microdrive-compatible. Polyimide 12 µm thick. 50 mm cable. Research use only.
