1. A surgical instrument, comprising:
a housing comprising a motor;
an elongate shaft defining a longitudinal axis;
an end effector extending from said elongate shaft, wherein said end effector comprises:
a first jaw;
a second jaw movable relative to said first jaw between an open position and a closed position in response to an actuation from said motor, wherein said first jaw and said second jaw are configured to capture tissue positioned therebetween; and
a segmented circuit positioned on one of said first jaw and said second jaw, wherein said segmented circuit comprises:
a first electrode configured to measure tissue impedance of the tissue captured between said first jaw and said second jaw at a first position; and
a second electrode electrically isolated and spaced apart from said first electrode, wherein said second electrode is configured to measure tissue impedance of the tissue captured between said first jaw and said second jaw at a second position that is different than said first position;
a battery;
a radio frequency (RF) energy generator powered by said battery and configured to transmit RF energy to the tissue captured between said first jaw and said second jaw ty way of said first electrode or said second electrode; and
a controller configured to:
control said motor based on the measured tissue impedances of the captured tissue;
energize said first electrode with a first amount of RF energy based on the tissue impedance measured at said first position; and
energize said second electrode with a second amount of RF energy based on the tissue impedance measured at said second position.
