1. A system that controls movement of a lancet, comprisinga housing;

  • an electronic drive force generator; and

    one or more processors coupled to the electronic drive force generator, wherein the one or more processors, cause force to be applied to the lancet to thereby cause the lancet to move in a first direction toward a target;

    monitor position and speed of the lancet as the lancet moves in the first direction;

    adjust the application of force to the lancet as the lancet moves in the first direction to achieve a desired speed of the lancet;

    adjust the application of force to the lancet when the lancet contacts the target so that the lancet penetrates the target within a desired range of speed and dwell in a target site for a selected dwell time;

    wherein the program instructions are executed to further cause the processor to cause force to be applied to the lancet to thereby cause the lancet to move in a second direction away from the target.
