The Syn-R1 electrode resting on a printed EEG trace
Technology

An electrode that reaches the scalp.

Pin-based and braided-anchor electrodes are real progress. None meet all four at once: scalp contact, wet-electrode impedance, no hair modification, minimal setup.

The design

A novel contact mechanism, in a familiar form.

Standard cap position, existing amplifier. What changes is how it makes contact.

A standard cup electrode rests on whatever is in its way, so dense, coily or braided hair holds it off the scalp. The compliant tip parts the hair and keeps travelling until it meets the scalp, then holds contact there.

That is why setup does not change from one participant to the next. Protected under patent application 2615593.7.

Beyond EEG

Built for EEG. Filed for every brain modality.

The filing covers fNIRS, tDCS and tACS as well as EEG.

EEG

Electrical recording

Where the mechanism is being proved first: passive, drop-in electrodes for reliable signal recording.

fNIRS

Optical recording

Functional near-infrared spectroscopy has the identical scalp-contact problem. The same mechanism applies to optical sensors.

tDCS

Direct stimulation

Transcranial direct current stimulation depends on stable, low-impedance scalp contact to deliver current safely and consistently.

tACS

Alternating stimulation

Transcranial alternating current stimulation carries the same requirement, and the same barrier for textured hair.

EEG is where the evidence and the need are clearest. The mechanism covers every modality that depends on scalp contact.

What it delivers

Four requirements, met together.

Others meet one or two. The requirement is all four at once, on every hair type. Which hair types we have tested, and which we have not, is published in the Human Hair Atlas.

Universal contact

Straight, wavy, curly, coily and afro-textured hair, with no preparation or modification.

Wet-electrode parity

Signal quality at impedance levels equivalent to clinical-grade wet electrode systems.

Minimal setup time

No extended preparation, no additional gel protocol, no specialist knowledge for diverse hair.

Research-grade output

Built to the requirements of academic research, clinical EEG and consumer BCI.

Fits your workflow

Drops into the setup you already have.

Same form factor as the cup and disc electrodes you use today, same connector, same amplifier. No new protocol.

Research edition reusable, clinical edition single-use. Both work for every participant, so you stop planning studies around who the hardware can record.

The detail

Where the rest of it lives.

The numbers, the recordings and the ordering detail have their own pages.

Evidence

Signal validation

Bench recordings against a clinical cup electrode, alpha-peak verification, and the survey behind the problem. See the validation
