It is commonly known as patient plate, grounding pad or return electrode. Its large and wide surface area promotes low current density, which in turn can be safely directed out of the patient's body during an electro-surgical procedure to prevent burn. These pads offer extra patient safety by signaling the system to shut down if the patient is not in complete contact with the pad.
