The end effector assembly can include a jaw assembly including a first jaw member and an opposing second jaw member that can be pivotably coupled to the first jaw member at a fulcrum. The jaw assembly can be movable between a first position and a second position. An electrode can be arranged on an inner surface of the first jaw member or the second jaw member. The electrode can include a plurality of segments, such as can be arranged to be sequentially extending outward in a row away from the fulcrum.
