Dry sensors for SmartBCI wireless EEG

Dry sensors for SmartBCI wireless EEG

Dry cap top view

SmartBCI wireless EEG systems now support both standard wet electrodes and caps with dry sensors.

We have upgraded the EEG amplifier and design special EEG cap with active electrodes with soft dry sensors. Now all SmartBCI system are compatible with both types of electrodes without any modification. You can now order extra 21 channel dry cap for your SmartBCI system in addition to your clinical kit with wet electrodes. Dry EEG cap includes 19 EEG channels + Common REF + GND.

Of courser the signal-to-noise ration is lower for dry sensors comparing to standard wet electrodes that require EEG gel or conductive past. But there is no perfect choice of electrodes that fit all cases and population groups. Instead, the needs of the research and experiment should be analyzed in detail, in order to carefully define the set of electrodes that will be used.

SmartBCI dry sensor assembly

The active electrodes have a pre-amplification module right after the sensor conductive material. This allows the signal to be amplified before additional noise is acquired between the electrode and amplifier itself that would capture, process the raw EEG signal.

Dry electrodes could be better choice for following research and clinical application:

  • Neurofeedback and other neurorahabilitation
  • Brain Computer Interfaces (BCI) design
  • Peak Performance in sports
  • Group EEG and etc.

Be aware that impedance measurement like evaluation of electrodes quality installation is not available for dry sensors. Impedance values for them are much higher comparing to wet electrodes and can exceed 100-250 kOhm, We use special technique in EEGStudio to provide clear feedback to the user about quality of electrodes placement. It based on 50/60 Hz noise level.

      Dear Dr. Sefa, you can request quotation it by e-mail or contact form. The cap is comparable to SmartBCI x24 system only. So, be aware that it is not sold like stand alone product.

      The cost of the system depends on type and number of caps. It starts from about 6k EUR

    Dear Sir/Madam,

    I hope this message finds you well. I am writing to inquire about the pricing of dry electrode caps with 19 active positions. Additionally, I am interested in learning about compatible amplifiers, their prices, and whether specific software is necessary for signal analysis. If software is required, I would appreciate information on its cost, or if alternative software solutions can be used (EEGlab, proQEEG).

    The intended use of these equipment is for both clinical applications and research purposes. Your prompt response with detailed information would be greatly appreciated.

    Thank you for your attention to this matter. I look forward to your reply.

    Best regards,

    Adrián Galiana
