1. A body fluid sampling system for use on a tissue site, the system comprising:

  • an electro-magnetic drive force generator;

    a plurality of penetrating members operatively coupled to said electro-magnetic drive force generator, said force generator moving each of said members along a path out of a housing having a penetrating member exit, into said tissue site, stopping in said tissue site, and withdrawing out of said tissue site;

    a plurality of analyte sensors, each of an analyte sensor of the plurality of analyte sensors being associated with a penetrating member;

    a flexible support member coupling said penetrating members to define an array, said support member being movable and configured to move each of said penetrating members to a launch position associated with said force generator;

    said electro-magnetic drive force generator configured to be controlled to follow a predetermined velocity trajectory into the tissue and out of said tissue; and

    a human interface providing at least one output, the human interface including a sensor for detecting audio commands.
