Abstract: An electrosurgical return electrode is disclosed. The return electrode includes a first and second flexible conductive material layers and a material layer disposed between the first and second conductive material layers. The material layer is transitionable between a solid state and a non-solid state, the material layer is also configured to melt upon an increase in temperature beyond a predetermined threshold, thereby increasing conductivity between the first and second conductive material layer.
