An electrical stimulator device composed of:

• a minimum of one electrode belonging to a group that contains type-1 and/or type-2 electrodes supported by a first supporting device formed as a rigid penetrating device,
• whereas the type-2 electrodes are adapted to adjust an electric field in a volume inside an animal, the volume being inside an external surface of the animal or at a surface of the animal, or inside an internal organ of the animal and the type-1 electrodes are adapted to apply electrical stimulating current to and/or from the rigid penetrating device,
• wherein the rigid penetrating device is capable of being inserted into at least part of the volume inside the animal or inside an organ of the animal, is adapted to either inject an electric current in its surroundings and/or to create an electric field in its surroundings capable of applying a directive force on existing electric charges in its environment,
• wherein the rigid penetrating device is adapted to be inserted into at least part of the volume inside the animal or inside an organ of the animal for a time no longer than 12 hours.
