An apparatus comprising a housing, a reservoir comprising a fluid and having an openable end, an applicator having a first major surface comprising a microneedle array, a pathway communicable between the openable end and the microneedle array, the housing supporting independently the applicator and the reservoir, a first stored energy device actuatable for applying force to the applicator to accelerate the applicator in a direction generally normal to the first major surface, and a second stored energy device actuatable for automatically opening the openable end, such that the openable end and the pathway are in fluid communication, and wherein the actuated second stored energy device forces the fluid through the openable end, the pathway, and the microneedle array, and wherein the first and second stored energy devices are comprised of at least one stored energy device from a group consisting of spring devices, gaseous propellants, chemicals, electrical devices, and combinations thereof.
