: These include a pre-amplifier within the electrode itself. This reduces noise and interference, making them more resilient to movement, though they are more expensive and heavier than passive versions.
: These are the most common type and consist of simple metal disks (usually gold or silver/silver chloride). They require an external amplifier and often use conductive gel to reduce skin-electrode impedance.
You can find specialized EEG equipment through various suppliers depending on your needs: EEG (electroencephalogram) - Mayo Clinic
: If buying gel-based electrodes, you will also need to purchase conductive gel and skin preparation paste. Note that pre-gelled electrodes have a limited shelf life (typically around 30 days) once the package is opened. Where to Buy
