1. An applicator for a microprojection array, comprising:
an energy-storing element having a first stable configuration and second stable configuration, wherein application of force to the energy-storing element causes it to transition from the first stable configuration to the second stable configuration, and wherein the force necessary for the energy storing element to transition from the first stable configuration to the second stable configuration is lower than the force necessary for the element to transition from the second stable configuration to the first stable configuration;
an actuating member that can convey external force to the energy-storing element,
a microprojection-holding member connected to the actuating member and which is acted on by the energy-storing element when it transitions from the first stable configuration to the second stable configuration,
an outer cover with an opening into which the actuating member fits slidably,
a skin-contacting member comprising a portion which can lie flat against skin, wherein the skin-contacting member fits the outer cover and contacts the energy-storing element when it is in its first configuration.
