Abstract
An electrosurgical return electrode is disclosed. The return electrode includes an intermediary layer formed from a dielectric material, the intermediary layer having a top surface and a patient-contacting surface. The return electrode also includes a capacitive return electrode formed from a conductive material disposed on the top surface of the intermediary layer and a resistive monitoring electrode formed from a conductive material disposed on the patient-contact surface of the intermediary layer.
