14. A system comprising a mechanical actuator configured for microneedle delivery, the mechanical actuator comprising:
a foldable biasing member comprising a first end and a second end, the foldable biasing member including a foldable portion comprising a flexibly resilient material having a flexibility permitting the first end and the second end to be foldable toward one another for movement from an expanded state toward a collapsed state in which the mechanical actuator fits within a volume sized to fit within a capsule, the flexibly resilient material further having a resiliency that biases the first end and the second end apart from one another for movement from the collapsed state toward the expanded state; and
a holder hingedly attached with the first end of the biasing member by a hinge distinct from the foldable portion of the biasing member such that the holder is pivotable about the hinge relative to the first end of the biasing member, the holder comprising a support surface configured for supporting a carrier bearing an array of microneedles, the support surface configured for supporting the carrier for outward movement for deployment of the microneedles in response to movement from the collapsed state toward the expanded state.
