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.

1-5. (canceled)
An electrosurgical return electrode, comprising:
- a return electrode pad having a patient-contacting surface configured to conduct electrosurgical energy;
- and
- a ferromagnetic material layer disposed on the return electrode pad, the ferromagnetic material layer including a magnetic field and at least one temperature sensing switch, the ferromagnetic material layer configured to lose magnetic flux at a predetermined temperature threshold thereby actuating the at least one temperature sensing switch.
