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

  • a drive force generator a plurality of penetrating members operatively coupled to said 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. a position sensor configured to provide an indication of a position of the penetrating member during actuation; and

    a user interface coupled to a processor, wherein in response to an input at the user interface by a user the processor provides an input to the drive force generator of a lancing penetration parameter selected from at least one of, penetrating member depth of penetration, velocity, braking, or retraction.
