An EFI (exploding foil initiator) or slapper detonator, including a explodable foil (or bridge), a flyer plate and a barrel plate having a movable barrier to close a barrel in a safety mode and for opening the barrel in an arming mode, wherein the movable barrier slides from a closed (safety) positi

An EFI (exploding foil initiator) or slapper detonator, including a explodable foil (or bridge), a flyer plate and a barrel plate having a movable barrier to close a barrel in a safety mode and for opening the barrel in an arming mode, wherein the movable barrier slides from a closed (safety) position to an open (armed) position under the control of a MEMS (microelectromechanical system) energetic actuator. The slidable barrier is maintained in the closed position by one or more locking devices of the MEMS energetic actuator until predetermined stimuli are detected to cause the locking device(s) to release the slidable barrier, thereby arming the EFI or slapper detonator.
