Edge Single-Shank 32-Channel Probe, 5 mm
Sites spread along the shank — linear and edge layouts for depth profiling
A single mid-length shank with sites along the shank's edge, closest to the tissue the probe faces. Among the 371 probe designs in the design space it is mid-range: 32 sites (a common choice — 155 of 369), 5 mm shanks (a common choice — 107 of 363), a 3.13 mm-deep site array (90th percentile), 393 sites/mm² (62nd percentile) and a 0.95 mm³ neural interface (69th percentile).
Large sites read a wider patch at lower impedance, suited to field potentials and multi-unit activity, spaced for a laminar profile. The mid-length shank reaches structures a few millimetres down.
Orders as a probe-plus-package assembly, in 13 package configurations. Silicon 15 µm thick. Z-coat available. Research use only.
