1. A device for transcutaneous electrical stimulation of a trigeminal nerve, comprising:
an elongated symmetrical support having at least one electrode pair and at least one microcontroller unit, the support having two lateral zones and an insulating central zone, each lateral zone having one electrode of the electrode pair and at least one electric circuit configured to supply to the electrode pair electric pulses having a predefined intensity, the at least one electric circuit being connected to the at least one microcontroller unit, the microcontroller unit being configured to measure an intensity of the supplied pulses and to steer the pulses, the support configured to be applied on a forehead of a person's face in a supraorbital region such that afferent paths of supratrochlear and supraorbital nerves of an ophthalmic branch of the trigeminal nerve are covered; and
an auditory signal control mechanism configured to control an auditory signal, the auditory signal control mechanism being connected to the at least one microcontroller unit and being configured to create the auditory signal when the measured intensity is different from the predefined intensity;
wherein each electrode pair is in contact with a self-adhesive conductive gel, the conductive gel at least partially covers one surface of the support for attaching the support to the forehead and is applied to the two lateral zones and is not applied to the insulating central zone.
