New EEG Cap Fully Dry Electrode Compatible with OpenBCI ULTRACORTEX_MARK Series | Instrument Parts & Accessories

New EEG Cap Fully Dry Electrode Compatible with OpenBCI ULTRACORTEX_MARK Series | Instrument Parts & Accessories

New EEG cap (plastic accessories are 3D printed), fully dry electrode (no conductive paste), compatible with OpenBCI ULtracortex_Mark3/4 series EEG cap, flexible configuration, multiple positions can be randomly matched, sticking scalp is firm

1. Apply to any type of head

Easterners and westerners head type is different, the eeg in abroad, especially the development of European and American countries is more rapid, so most of the electrical products (almost monopoly by foreign electrical chip) are foreign design and production, eeg cap in a considerable number of foreign or head frame structure is according to the European and American white head type to design, may I

We don't usually notice the difference between the European and American white and Asian head shape, so let's make a simple comparison:

The head type of the European and American jaw is relatively narrow, the forebrain to the back of the brain is longer, from the top of the head looking down like a duck egg;Asian head shape is closer to the rounded square and round, comparing hubei wide, forebrain to afterbrain is shorter, looking down from the top of your head to see more like a kind of circular, below is a programme about Japan Europe and the United States the characters head shape and the differences between the Asian characters head type pictures, the picture very image describes the difference of Europe and the United States and Asia head type (and even affected the anime character modelling & gt;_<)

2. It fits better

The cloth used to fix the dry electrodes is a flexible elastic band, and the dry electrode holder is embedded in these elastic bands. When it is tightened and clicked, it will be firmly attached to the scalp, making it fit better than the normal fixed frame type (rigid) EEG cap

3. More flexible configuration of dry ground electrode contact position

The flexible fixing belt has openings reserved for the electrode holder every 2cm or so

Precautions for the use of EEG caps

1. Suggestions for EEG cap installation

The electrode installation distribution should not be too marginal (too marginal installation may lead to insufficient electrode pressure or inability to be perpendicular to the scalp, affecting test performance)

It is recommended that all wires from the dry electrode + the clip electrode be twisted into one strand. If the length of the strand is excessive, it is recommended that the strand be rolled up or folded up and taped to shorten the length of the strand

2. Pre-test preparation

Keep hair, scalp and earlobes clean and clean (oily dirt will affect the contact performance and corrode the electrodes, so it is recommended to use cleaning paste to clean hair and left and right earlobes in advance, and keep hair and scalp dry and fresh after cleaning)

3. Test recommendations

The electrodes should be attached to the scalp

The axis of the electrode disc should be perpendicular to the scalp surface

The ear clip electrode is clamped on the earlobe. After clamping, squeeze the two sides with your hand and keep it close to the earlobe

4. Postural advice

Try to keep your body still during the test to avoid sudden shaking

5. Measures to improve performance and reduce interference

The testing environment can be a headache for buyers in different working environments, so try to turn off any equipment with low frequency interference (air conditioners, fans, microwaves, ovens, laptop power adapters).Etc., the computer itself cooling fan can be ignored), the ideal environment is: only OpenBCI + PC work

If the waveform is not ideal, you can try to make the EEG board + battery box not connected to the desktop, etc., and hold it in the air with your hand for test. If possible, it can be fixed on the EEG cap (it is suggested to fix it on the EEG cap).

If the waveform is not ideal, try moving the board + EEG cap away from the test computer

Statement:

1. The hard frame part is PLA plastic, which is rapidly molded by 3D printer. Due to the immature civil and industrial 3D printing technology, the 3D printed parts cannot reach the standard of injection moulding parts in terms of appearance and strength, especially in terms of appearance;Our 3 d printer for ordinary civil 3 d printer, use the most commonly used cascade technology, considering the accuracy and limitation of inverse ratio, we use the average accuracy of rapid prototyping, but does not affect the function of each module and performance, we consider is practical, exterior nature cannot be compared with injection molded parts, if you have any requirements please carefully taken close to appearance,We do not accept unreasonable returns based on appearance (irrelevant to function), so after taking the photo, we fully agree with this statement - appearance factors can be ignored.
