Abstract
This invention relates to a MEMS detonator, in particular the production of MEMS scale detonators via the use of a microreactor (3). The invention further lies in a reproducible manufacturing method of MEMS scale detonators, for use in safety and arming units (SAU), which are used in warheads and munitions. A warhead comprising a MEMS detonator may find particular use in increasing the IM compliance of munitions. The method involves the use of high pressure input of two solutions (2, 2a) into a microreactor (3) to form an in-situ precipitation reaction, which furnishes an initiatory (i.e. primary) explosive, wherein the explosive and supernatant liquid is directly fed into a microchamber, using the microcavities in the septum as a MEMS sieve to retain the explosive and form a MEMS detonator.
