1. An integrated system for delivering a microneedle array, the system comprising:

  • a housing having a height of at least 2 mm and no greater than 3.0 cm, a cavity therein, and including an applicator device;

    a carrier assembly including a solid microneedle array, wherein a portion of the carrier assembly is attached to the housing proximate the cavity and is in contact with a portion of the applicator; and

    wherein neither the carrier assembly nor the array are attached to the applicator device;

    a stored energy device comprising one or more bifurcating-springs that are capable of undergoing a shape change as a result of a predetermined force normal to a major plane of the stored energy device, wherein at least a portion of the stored energy device is located within the housing; and

    wherein the stored energy device can be actuated to apply force on the carrier assembly;

    wherein the applicator device further comprises an actuator; and

    wherein the actuator is movable within the housing in a certain direction orthogonal to the major plane of the stored energy device and the actuator comprises a screw received in a series of helical threads in the housing.
