1. A lancing system configured to drive a lancet during a lancing cycle and used on a tissue site, the system comprising:

  • a controllable electronic lancet driver coupled to the lancet;

    a position sensor coupled to the controllable electronic lancet driver, the position sensor configured to detect position and velocity of the lancet in the tissue site; and

    a processor coupled to said controllable electronic lancet driver, said processor configured to adjust velocity of the lancet to advance the lancet at a first desired velocity in a first layer of tissue, at a second desired velocity in a second layer of tissue, and at a third desired velocity in a third layer of tissue based on feedback of the position and velocity of the lancet from the position sensor.
