Research in a novel integrated chip of safe and initiation control

This paper presents a novel safe and initiation controlled integrated chip based on MEMS metal bridge in a microfuze for military purpose. The proposed chip is made of: (1)one arming function and (2) one sterilization function. The arming function keeps the fuze in safe state normally and to be armed when the fuze is respect. For that, a short circuit to the electrical ground is melted when the igniting circuit connected to the power supply and the igniting capacitance is to be charged. If the fuze is not working properly, the igniter can be sterilized meaning that the system's ignition capability is definitively removed. All these functions are working properly with two kinds of micro switches based on MEMS metal bridge: one short circuit and one ETBS. Due to the application requirements (the fuze is used once after a long storage, all components must have a high level of safety and reliability and the power consumption must be minimized), In this paper, we present a novel integrated chip of safe and initiation control based on MEMS metal bridge. Through simulation and preproduction, good performance in safe, action time and power consumption were founded. The safe and initiation controlled integrated chip could be manufactured easily in great amount and can also be applied in some fields of high-energy control. If necessary the chip can be integrated with control circuits in future.
