SiNAPS 4-Shank 1,024-Channel Probe
CMOS active-pixel silicon probe — 1,024 simultaneous channels across 4 shanks
Four mid-length shanks side by side, spread for lateral coverage across columns, with an active pixel beneath every site. Among the 371 probe designs in the design space it sits at the top: 1,024 sites (100th percentile), 5.5 mm shanks (52nd percentile of the 366 measured), a 3.77 mm-deep site array (93rd percentile), 158 sites/mm² (43rd percentile) and a 4.75 mm³ neural interface (97th percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, packed densely enough to track a unit across neighbouring sites. The mid-length shanks reach structures a few millimetres down.
Orders as a probe-plus-package assembly, in 2 package configurations. Silicon 50 µm thick. Optical stimulation runs from a separate laser or LED source. Research use only.
