Electrode arrangement for measuring biopotentials on a person's head

A device comprising:

• an electrode arrangement with a plurality of electrodes for measuring electric signals on a face surface of a head of a user and behind an ear of the user, wherein the electrodes of the plurality of electrodes are wet electrodes;
• a carrier structure;
• wherein the carrier structure at least partially defines a relative position of the electrodes to one another;
• and
• wherein the carrier structure is shape-stable within a tolerance range without external force exerted by a user and deformable under external force exerted by the user, in order to change a distance between two adjacently arranged electrodes and to area-comprehensively adapt to face and head structures,
• wherein the carrier structure is configured to position at least a part of the electrode arrangement on the face surface and behind the ear;
• wherein the carrier structure is configured in the shape of a net structure with branching connecting ribs that follow a course of the face surface;
• and
• wherein the branched connecting ribs comprise a rib width corresponding to, at most, three times the electrode diameter of an electrode of the plurality of the electrodes.
