The invention provides an end effector comprising a clamp arm and an ultrasonic blade configured to be acoustically coupleable to an ultrasonic transducer and electrically coupled to one pole of a generator. The clamp arm includes a clamp and a conductive polymer clamp arm pad. The clamp arm may include a non-conductive layer and a conductive layer arranged in a sandwich-like configuration to electrically couple to opposite poles of the generator. The clamp arm may include a composite material clamp arm pad attached to the clamp, the composite material clamp arm pad including a non-conductive layer and a conductive layer to couple to opposite poles of the generator. The clamp arm may include a bracket attached to the clamp, and a clamp arm pad including a non-conductive pad and a conductive pad to couple to opposite poles of the generator. 本发明提供了一种包括夹持臂和超声刀的端部执行器，该超声刀被配置为能够声学联接到超声换能器并且电联接到发电机的一个极。该夹持臂包括夹钳和导电聚合物夹持臂垫。该夹持臂可包括以夹层状构型布置的不导电层和导电层以电联接到该发电机的相反极。该夹持臂可包括附接到该夹钳的复合材料夹持臂垫，该复合材料夹持臂垫包括不导电层和导电层以联接到该发电机的相反极。该夹
