MEMS Inertial Switch for Military Applications

open access: yesProceedings, 2017
We developed a MEMS inertial switch (hereafter, the switch) for an ignition system of missiles. The developed switch consists of four folded beams and a plate suspended by the beams, analogous to a well-known spring-mass system.
