Patent ID: 7596400

Claim:
An electrode detector for monitoring biopotential or other physical magnitude of a tissue of a subject, in which the electrode detector comprises a contact electrode part and an attaching part, wherein the contact electrode part and the attaching part are attached to a flexible conducting wire in such a way that the contact electrode part and the attaching part are separate from each other in order to make an effect that the contact electrode part yields, while connected to the flexible conducting wire, although variable forces would be directed to it due to the movement of the tissue thereby reducing the disadvantageous mechanical stress and irritation effects of the contact electrode part on the tissue to be monitored, while the electrode detector is placed against the tissue in such a way that an attaching element or elements of the attaching part keep the electrode detector in place, or while the electrode detector is implanted wholly within the tissue in which case the forces directed to the electrode detector by the surrounding tissue keep the electrode detector in place, and while a voltage signal is conveyed from the contact electrode part to the attaching part through, the conducting wire and while a recorded signal is further transmittable from the attaching part to a signal registering system, which the electrode detector includes; a ball-shaped contact electrode part, a flexible conducting wire, a free-form and free-shaped attaching part, electronics coupled to the conducting wire, wherein the contact electrode part comprises a covering part which is non-toxic to tissue material and conducts electricity, and an inner part, and wherein the conducting wire comprises another covering part which is non-toxic to tissue material and isolates electricity, and another inner part which conducts electricity, and wherein the electroconductive covering part of the contact electrode part is galvanically, or capacitively, or indirectly through an electronic circuitry in the contact electrode part itself, connected to the electroconductive inner part of the conducting wire, and wherein the attaching part is connected galvanically, or non-galvanically, or indirectly through an electronic circuitry in the attaching part, to the conducting wire, and wherein the attaching part is adapted to be anchored by attaching elements/materials in it or some external attaching elements/materials near the subject to be measured.
