1. An end-effector, comprising:
a clamp arm; and
an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator;
wherein the clamp arm comprises:
a clamp jaw defining a plurality of zones along the clamp jaw;
at least one spring disposed in each of the plurality of zones, wherein the spring bias force of a first spring in a first zone is different from the spring bias force of a second spring in a second zone; and
a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator, wherein the cantilever electrode is disposed along the plurality of zones and in contact with the each of the springs to apply a variable spring bias along the length of the cantilever electrode, wherein the cantilever electrode is fixed to the clamp jaw at a proximal end and free to deflect at a distal end.
