1. An electrode apparatus configured to be applied on a skin with hair of a mammal for measuring an electrical bio-signal, wherein the electrode apparatus comprises:
first and second cylindrical chambers,
the first cylindrical chamber comprising a wall, which is configured to form a cavity within the first cylindrical chamber, and having both ends open,
the second cylindrical chamber comprising a roof at a first end of the second cylindrical chamber, a second end of the second cylindrical chamber opposite to the first end being open, the roof covering a combination of the first and second cylindrical chambers, and
at least one electrode; and
an elongated structure, within both of the first and second cylindrical chambers, comprising a first portion parallel to a central axis of the first and second cylindrical chambers, a first end of the elongated structure, the first end of the elongated structure belonging to the first portion, being attached to the roof, and at least one second portion, each comprising a second end opposite to the first end, the at least one second portion being configured to deviate from a direction of the central axis of said first and second cylindrical chambers; and
wherein the elongated structure is configured to rotate in order to bundle hair, the bundle of the hair being formed on and around the second portion of the elongated structure for exposing skin without the hair within both of the first and second cylindrical chambers, when applied to the mammal so as to improve a contact of the at least one electrode with the skin of the mammal.
