Tetrode/Linear Single-Shank 32-Channel Probe, 7 mm
Parallel shanks at a pitch fixed in fabrication — the same layer across several columns
A single long shank with tetrode groups along a linear run, isolation at set depths with a profile between. Among the 371 probe designs in the design space it is mid-range: 32 sites (a common choice — 155 of 369), 7 mm shanks (63rd percentile of the 366 measured), a 0.52 mm-deep site array (29th percentile), 100 sites/mm² (34th percentile) and a 0.57 mm³ neural interface (45th percentile).
packed densely enough to track a unit across neighbouring sites. The long shank reaches deep targets.
Orders as a probe-plus-package assembly, in 3 package configurations. Silicon 15 or 50 µm thick. Z-coat available. Research use only.
