1. A method of controlling a lancet velocity profile, comprising:

  • a) measuring a velocity of a moving lancet at a position;

    b) comparing the measured velocity of the lancet with a lancing velocity vs. position profile for the lancet at the position; and

    c) applying a force to the lancet to adjust the velocity of the lancet to accelerate, coast, or decelerate at the position according to the lancing velocity vs. position profile until the lancet reaches and settles at the maximum displacement position;

    wherein a processor compares the measured velocity of the lancet to the appropriate velocity of the lancet at the position and calculates the force to be applied to the lancet to adjust the velocity of the lancet.
