64-CHANNEL μECoG · 30 kS/s · 1.82 ms

Intent, decoded
before the hand moves

Synapse reads cortical surface potentials through a 1.8 mm-thin array and turns them into device commands in under two milliseconds — faster than the signal reaches the muscle. The raster on the right is a simulation of that stream, not a recording of a person.

Thin enough
to be forgotten

The array sits on the cortical surface, under the dura — 1.8 mm thin, 64 electrodes at 2.5 mm pitch. No puncturing tissue, no threads into the parenchyma. Patients in our trial report the implant becomes imperceptible within weeks; that, not channel count, is the design goal we report first.

The die photographs are of the actual implant, not renders. What you see is what a surgeon holds.

Numbers, with their conditions

Measured performance — metric, value, measurement condition
Metric Value Condition
Decode latency 1.82 ms p50 · on-device inference · 12 participants
Raw sampling 30 kS/s per channel · 24-bit ΔΣ
SNR 18.4 dB referenced to skull electrode · chronic week 26
Gesture classes 11 offline, cross-validated · 94.1% ± 1.8
Wireless link — transcutaneous power + 2.4 GHz telemetry

All values from the first-in-human trial (N=12), 2025-09 – 2026-06. Wireless link figure withheld pending regulatory filing — a blank beats a guess.

What we will not do

  • No neural advertising

    Decoded signals are commands, not content. We do not build — or license — emotion or attention inference.

  • Participants can leave

    Explantation on request within 30 days, at our cost, at any point in the trial. Three participants have exercised it.

  • Raw data stays in the vault

    Raw neural data never leaves our encrypted cluster. Published figures are aggregate statistics, as on this page.
