US Patent 7695430 Reverse current controlling electrode with oversize backing

A medical electrode includes a moderately conductive flexible member having a top side and a bottom side with a connector and contact with a flexible member top side for establishing electrical contact with an external apparatus. An oversize non-conductive flexible sheet covers the conductive flexible member top and the connector and a highly conductive ink pattern is disposed on a conductive flexible member bottom side. A moderately high conductive hydrogel adhesive disposed on the conductive flexible member bottom side and covering the conductive ink pattern is provided for adhering the electrode to a patient's skin.
