Patent ID: 8825128

Claim:
A sensor for measuring biosignals, the sensor comprising at least one electrode comprising: a substrate comprising a flexible non-conductive material; a conductive layer configured to transfer electrical signals; a gel layer configured to transfer electrical signals; a foam element; and a barrier layer configured to protect the conductive layer and transfer electrical signals, wherein: a portion of the conductive layer is deposited on a first area of a surface of the barrier layer, the barrier layer is deposited on the substrate so that a portion of the barrier layer in contact with the conductive layer is positioned between the substrate and the conductive layer, the gel layer is deposited on a second area of the surface of the barrier layer so that the gel layer covers only a part of the barrier layer, and a portion of the foam element is deposited on a third area of the surface of the barrier layer, wherein the third area is between the first area and the second area.
