Analytical scalp electrode, reusable

Analytical scalp electrodes are reusable, noninvasive conductors placed on the scalp to detect and transmit brain electrical activity for monitoring or recording by devices such as EEG systems, sleep monitors, or evoked potential recorders. They are typically small cups, disks, or stars made of conductive materials like gold, silver, or titanium, often with insulated wires, and may be sold as individual units or sets but are not preconfigured EEG caps.

As reusable devices, these electrodes are intended for multiple uses after proper cleaning and disinfection according to manufacturer instructions. They are regulated as medical devices based on their intended use and design, with classification determined by jurisdiction-specific rules, and are supplied for use in clinical neurodiagnostic settings where repeated application is required.
