Abstract
An applicator for a microprojection array is described. In one embodiment, the applicator comprises an energy-storing element. Application of force causes the compressed energy-storing element to extend or transition from first and second configurations, releasing stored energy to deploy a holding member in the application which is configured to hold an array of microprojections. In another embodiment, the applicator comprises an energy storing element with two stable configurations, a first stable configuration and second stable configuration. Application of force causes the energy-storing element to transition from the higher energy first stable configuration to the lower energy second stable configuration, releasing the difference in energies of the two states to deploy a holding member in the application which is configured to hold an array of microprojections.
