High explosive coatings and inks suitable for use in micro-electronic initiators for micro-electro-mechanical mechanisms used as safe and arm devices, are prepared from coating compositions of crystalline energetic materials and applied using various methods. These methods include wiping and spraying, as well as, pressure applications using a syringe or the like, and application of thick film ink to write specified patterns on a selected surface. A volatile mobile phase may be added to the coating composition to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the selected surface.
