1. A surgical stapling system comprising:

  • an elongated shaft assembly configured to transmit actuation motions from an actuator;

    an end effector for compressing and stapling tissue, the end effector operably coupled to the elongated shaft, the end effector comprising;

    an elongated channel;

    an anvil having a staple forming surface thereon, the anvil moveable relative to the elongated channel between an open position and a closed position; and

    a staple cartridge removably positioned within the elongated channel, the staple cartridge comprising;

    a cartridge body having a tissue contacting surface in a confronting relationship with the staple forming surface of the anvil; and

    a plurality of staple drivers within the cartridge body each supporting a staple; and

    a tissue thickness compensator operable to be positioned between the anvil and the staple cartridge, the tissue thickness compensator configured to be captured by the staples and assume different compressed heights within the staples, the tissue compensator comprising first conductive elements, wherein the first conductive elements comprise a wire mesh;

    wherein the system is operable to determine a property of tissue compressed between the anvil and the staple cartridge.
