1. An apparatus, comprising:

  • a housing;

    an analyte sensor disposed in the housing; and

    an insertion unit disposed in the housing, the insertion unit operatively coupled to the sensor and configured to place at least a portion of the sensor under a skin layer, wherein the insertion unit is configured to remain disposed in the housing after sensor placement;

    wherein the insertion unit includes a compressible introducer mechanism coupled to an introducer, the compressible introducer mechanism configured to displace at least a portion of the sensor and the introducer through the skin layer to an insertion position under the skin layer;

    wherein the compressible introducer mechanism moves from a non-compressed state to a compressed state in response to a manual force applied to the compressible introducer mechanism, wherein when the compressible introducer mechanism moves from the non-compressed state to the compressed state, the at least the portion of the sensor and the introducer are inserted through the skin layer to the insertion position;

    wherein removal of the manual force from the compressible introducer mechanism causes the compressible introducer mechanism to move from the compressed state to the non-compressed state and automatically withdraw the at least the portion of the introducer from under the skin layer while retaining the at least the portion of the sensor at the insertion position; and

    furtherwherein the compressible introducer mechanism is contained within the housing when the compressible introducer mechanism is in the non-compressed state and the compressed state.
