As information,intelligence and miniaturization progresses in ammunitions,Micro‑Electrical‑Mechanical System(MEMS)based initiator was derived to meet the need of the information of energy‑transferring,miniaturization on structure and integration of energy sequence.As one kind of a system‑level MEMS initiator,the present micro fire‑train was integrated based on initiation detonation mechanism of the flyer impacting the next booster explosive.By focusing on the application and technical requirements of micro fire‑train,the state‑of‑art of the fire‑train was reviewed from five aspects,including the micro‑heater design and firing energy control,microscale detonation energy control and devitrization,energy transmission and safety control,micro fire‑train design and integration,and reliability evaluation of the fire‑train.Based on the analysis of state‑of‑art of micro fire‑train,some suggestions for future development were proposed,and the key points for the further development of micro fire‑train are discussed:strengthen the basic research of initiation and detonation mechanism under micro scale;promote digital engineering and improve forward‑design capability;build mass production capacity including element‑level,component‑level and system‑level of the micro fire‑train;enhance the qualification and improve technology maturity of micro fire‑train.It is vital useful for the peers to pay more attention on the design,fabrication,test and evaluation of the micro fire‑train.
