Claim 10:
11. A surgical instrument, comprising:
a housing;
an ultrasonic transducer; and
an end-effector comprising:
a clamp arm; and
an ultrasonic blade configured to acoustically couple to the ultrasonic transducer and to electrically couple to a pole of an electrical generator; and
wherein the clamp arm comprises:
a clamp jaw; and
a cantilever electrode configured to electrically couple to an opposite pole of the electrical generator, wherein the cantilever electrode is fixed to a proximal end of the clamp jaw and is free to deflect at a distal end of the clamp jaw, wherein the cantilever electrode comprises a distal conductive element attached to a distal end of the cantilever electrode, wherein the distal conductive element is configured to generate a signal to indicate contact between the ultrasonic blade and the distal conductive element.
