1. An agent injection device including electrical components, comprising:

  • a housing;

    the housing including a first housing and a second housing, where the first housing being larger than the second housing, the first and second housings having dissimilar shapes, the first housing configured to house a battery, and the second housing configured to house the electrical components;

    a needle with an interior channel, the needle positionable in the housing;

    an agent container coupled to the needle and positioned at the housing;

    an actuator processor coupled to a position sensor;

    a human interface processor that is lower power and slower than the actuator processor, the human interface processor configured to run intermittently to conserve power for the human interface processor, the human interface processor configured to control power for the actuator processor and is a timer for the actuator processor so that the actuator processor does not remain on for long periods of time;

    a human interface coupled to the human interface processor that allows a user to adjust a sampling setting; and

    a controllable drive force generator coupled to the actuator processor and configured to be coupled to the needle to advance the needle along a path into a tissue site to a selected depth of the agent.
