Disposable electrode for electro-stimulation

摘要

An electrode configured to provide electrical contact with a subject's skin and includes a conductive layer and a gel layer. The conductive layer spreads current and transmits electrical signals to and/or receives electrical signals from the subject's skin and has a first conductive surface through which electrical signals are transmitted to and/or received from the subject's skin. The first conductive surface is on a side of the conductive layer that faces toward the subject's skin if the electrode is installed on the subject. The gel layer is formed on the same side of the conductive layer as the first conductive surface. The gel layer has a first interface surface that directly contacts the subject's skin if the electrode is installed on the subject, and to conduct electrical signals between the subject's skin and the first conductive surface. The first interface surface has a surface area larger than that of the first conductive surface.

1. An electrode configured to provide electrical contact with a subject's skin and to transmit electrical signals from the subject's skin to an external electrical apparatus, wherein the electrode is further configured to receive electrical signals from the external electrical apparatus for transfer to the subject's skin, the electrode comprising:
a base pad configured to provide electrical insulation, wherein the base pad includes an opening; a conductive layer configured to spread current and transfer the electrical signals, the conductive layer having a first conductive surface through which the electrical signals are transferred, the first conductive surface being on a side of the conductive layer that faces toward the skin of the subject if the electrode is installed on the subject; a plate configured to transmit the electrical signals, wherein the plate includes ferromagnetic material configured to magnetically couple with the external electrical apparatus, the plate being arranged on the side of the conductive layer that faces toward the skin of the subject if the electrode is installed on the subject, wherein the conductive layer is arranged between the base pad and the plate; electrically insulating material configured to provide electrical insulation, wherein the electrically insulating material includes a second opening, the electrically insulating material being arranged on the side of the conductive layer that faces toward the skin of the subject if the electrode is installed on the subject, wherein the plate is arranged between the conductive layer and the electrically insulating material; a gel layer configured to conduct the electrical signals between the subject's skin and the external electrical apparatus, the gel layer being arranged on the side of the conductive layer that faces toward the skin of the subject if the electrode is installed on the subject, wherein the electrically insulating material is arranged between the plate and the gel layer, wherein the electrical signals received from the external electrical apparatus are transmitted through the opening of the base pad, through the conductive layer, through the second opening in the electrically insulating material, through the gel layer, and to the subject's skin.
