GENERAL DESCRIPTION
Our electroencephalography (EEG) sensor
has been especially designed for both classic
and localized EEG measurement. When a
cap is too intrusive, only a limited number of
channels are needed, or you’d like to
synchronously record EEG and non-EEG
biosignals, this is the perfect solution. The
bipolar configuration, with two measurement
electrodes detects the electrical potentials in
the specific scalp region with respect to a
reference electrode, which should be placed
in a region of low muscular activity. The
resulting signal is the amplified difference
between these two signals, eliminating the
common unwanted signals detected by the
surfaces. Its convenient form factor enables a
discrete placement in regions such as the
forehead, occipital, and others. Examples:
