Abstract
A return pad includes a backing, at least one return electrode, and at least one ring sensor. The backing has a top side, a bottom side, and a periphery. The return electrode is disposed on the bottom side of the backing layer and is adapted to connect to a current generator. The ring sensor(s) is disposed in substantial concentric registration with the periphery of the backing and is configured to connect to a measuring component. The measuring component is operable to approximate contact quality of the return electrode during electrosurgical application and is configured to communicate with the generator.
