Cap EEG kit 32 channels with 32 wet electrodes and 2 clips Electrode

Cap EEG Kit, 32 Channels with Wet Electrodes: Full-Head, High-Density EEG for IronBCI-32

A ready-to-wear EEG cap with 32 wet Ag/AgCl electrodes and 2 ear-clip electrodes, pre-placed on the international 10-20 system and pre-numbered to match IronBCI-32 channel by channel. Cover the whole head, from the forehead to the back of the head, with research-grade wet electrodes. Plug and play: every electrode ends in a standard 2.54 mm connector.

Why this kit?

• High-density, full-head coverage. 32 electrodes across the midline and both hemispheres, for brain mapping, connectivity and advanced BCI research.
• Best signal quality. Wet Ag/AgCl electrodes with conductive gel give low impedance and low noise, the standard for high-quality EEG.
• Made for IronBCI-32. Each electrode is numbered to its IronBCI-32 channel, so wiring is quick and the channel order is always right.
• Plug and play. Integrated cables with 2.54 mm connectors. No soldering, no adapters.
• Complete kit. Cap, 32 signal electrodes and both ear clips (reference and bias), all in one box.

Compatible devices

The EEG device and conductive gel are not included. Order them separately.

Electrode positions

Channel numbers are IronBCI-32 channels. T7, T8, P7 and P8 are the modern names for T3, T4, T5 and T6.

Specifications

How to use

1. Put on the cap so Fp1, Fpz and Fp2 sit on the forehead just above the eyebrows, and Cz is at the top of the head, halfway between the nose and the back of the head.
2. Apply conductive EEG gel to each electrode so it makes contact with the scalp through the hair.
3. Clip the two ear electrodes onto clean earlobes.
4. Plug each electrode into the IronBCI-32 channel with the same number, and the ear clips into the reference and bias pins on the channel 1-8 header.
5. Power IronBCI-32 from a USB battery and start the software.
6. Check the signal: blink a few times (spikes on the forehead channels), then close your eyes for 10 seconds (alpha rhythm rises on O1, Oz and O2).

Tips for a clean signal

• Clean the forehead and earlobes with an alcohol wipe before use.
• Use a gel made for EEG. A small amount per electrode is enough; too much can bridge neighbouring electrodes.
• Make sure the ear clips sit firmly: a loose reference makes every channel noisy.
• Bundle the cables together and keep them still. Moving cables show up as noise.
• After use, rinse the electrodes and cap with warm water to remove the gel, and let them dry fully before storing.
