Technical details and features of the Neurithm EEG Headband
WHAT IT IS
Neurithm is a device in the form of a flexible extension band with dry electrodes, an integrated electronic module and removable battery.
HOW IT WORKS
Neurithm is designed for daily comfortable use. It enables precise and reliable real-time monitoring (measuring and recording) of brain electrical activity through the head hair (the temples and the head) as well as bioelectrical activity of the forehead, face, head and eye muscles.
TECHNICAL PARAMETERS
4 EEG channels with a differentiation of myographic (EMG) and oculographic (EOG) components
Channel sampling rate — 250 Hz
Connection interface — Bluetooth LE
Minimum continuous usage — 12 hours
Measurable voltage range — ± 0,4 V
Battery current — 100 mА ± 10%
Battery charging time — up to 4 hours
UNIQUE FEATURES
Neurithm uses dry electrodes in form of spring-loaded gilded sensors that ensure EEG recording through hair of any thickness without any gel.
Two electrodes are placed on the temporal lobe regions, two on the occipital lobe regions (T3, T4, O1, O2 according to the international 10-20 electrode system). The gilded flat reference sensor is positioned on the forehead.
Such positioning helps recording raw EEG data both in a bipolar and monopolar mode (minimising forehead biopotential artifacts).
Neurithm uses the international 10-20 system with electrodes at positions T3, T4, O1, and O2
