1. A tissue penetrating system, comprising:

  • a housing member;

    a plurality of penetrating members positioned in the housing member,an electronic penetrating member driver positioned in the housing member for driving each of the plurality of penetrating members, the electronic penetrating member driver providing an electronic stop of penetrating members in a tissue site;

    a plurality of non-optical sensors, each of the plurality of non-optical sensors associated with a penetrating member positioned in the housing member, each of the plurality of non-optical sensors configured to receive a body fluid sample in response to a penetrating event of target tissue made with a penetrating member;

    a penetrating member transport device for carrying the plurality of penetrating members and moving each of the penetrating members to a launch position, the penetrating member transport device positioned in the housing member;

    a processor positioned in the housing member and coupled to a feedback control and to the electronic penetrating member driver and configured to provide for controlled velocity of a penetrating member in and out of a tissue site, the processor including a database that includes user profiles for setting penetration parameters of a penetrating member to create the puncture wound in the target tissue for a successful penetration and achieve a desired blood volume;

    wherein in response to the processor selecting a profile, the processor instructing a power delivery to the electronic penetrating member driver; and

    a position sensor coupled to the processor and a penetrating member, the position sensor detecting a movement of the penetrating member and generating position data in response thereto, wherein during a rearward displacement of a penetrating member in response to elastic tenting of tissue, the processor reads and stores position data generated by the position sensor and measures an amount of elastic tenting.
