1. A tissue penetrating system, comprising:

  • a housing member;

    a plurality of penetrating members positioned in a disposable in the housing member, the disposable having a plurality of penetrating member module portions each with a penetrating member channel, each of a penetrating member channel being parallel to a longitudinal axis of the disposable each of a penetrating member being free to slide in a respective penetrating member channel of the disposable with a sharpened tip of the penetrating member being withdrawn into a penetrating member channel to protect the tip and allow rotational motion between the disposable relative to the housing, a radial center of each penetrating member channel being disposed in a fixed, known radial distance from a longitudinal axis of the disposable to provide that each of a penetrating member channel is repeatably aligned in a functional arrangement with penetrating member channels of the disposable, the disposable configured to rotate about a pivot;

    a plurality of analyte sensors, each of an analyte sensors being associated with a penetrating member,an electronic penetrating member driver for driving each of the plurality of penetrating members;

    a processor coupled to the electronic penetrating member driver, the processor including a user customizable velocity profile for setting penetration parameters of at least one of the plurality of penetrating members to successfully create the puncture wound with a desired degree of painlessness, success rate, and blood volume;

    wherein the processor causes the electronic penetrating member driver to advance and retract said at least one penetrating member of the plurality of penetrating members with predetermined force to achieve said user customizable velocity profile; and

    a penetrating member transport device for moving each of the plurality of penetrating members into a position for alignment with and to be driven by the penetrating member driver.
