An electrode for establishing electrical connection between a leadwire and a surface includes a contact portion and a conductive bridge portion. The contact portion includes a conductive layer, an insulator layer on one side thereof, and an anchor or adhesive layer on the other side thereof for anchoring the contact portion to the surface. The bridge portion extends from the contact portion and is electrically connected with the conductive layer. The bridge portion includes a receptor to which the leadwire is attachable and a series of perforations which form a breakaway or yieldable connection mechanism for allowing the bridge portion to be partially pulled apart when applied to the surface. The series of perforations thus allow the receptor to move yieldably with six degrees of freedom of movement relative to the contact portion while still maintaining electrical connection with the conductive layer. Thus, when a pulling force is exerted between the leadwire and the contact portion, the exerted force is relieved without pulling the contact portion from the surface. Preferably, the bridge portion and receptor are an extension of the conductive layer and insulator layer beyond an end of the anchor layer. The receptor is also preferably forms a tab which is moved from a plane of the extension. The series of perforations ends in a circular aperture and forms a coil, though the series could also be at least two straight lines.
