Edge 2-Shank 30-Channel Probe, 4 mm
Silicon 3D probe platform — several 32-site 2D arrays, 64 to 256 channels, recording and stimulating
Two mid-length shanks side by side, spread for lateral coverage across columns, 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: 30 sites (30th percentile), 4 mm shanks (21st percentile of the 366 measured), a 3.52 mm-deep site array (92nd percentile), 4.69 sites/mm² (3rd percentile) and a 4.66 mm³ neural interface (97th percentile).
Small sites read a local patch at higher impedance, sharpening single-unit isolation, spaced widely to span a structure rather than resolve within it. The mid-length shanks reach structures a few millimetres down.
Orders as a probe-plus-package assembly, in 19 package configurations, 2 of them microdrive-compatible. Built for the Matrix Array platform: this 2D array installs in a Matrix package slot and is not assembled in other packages. Silicon 50 µm thick. Z-coat available. Research use only.
