To study the effect rule of the type and size for polysilicon bridge on the ignition performance of Al / Cu O energetic igniter,six kinds of energetic igniters with different shapes and sizes were prepared by integrating polysilicon with Al / Cu O multilayer films and the firing sensitivities of four sizes and two bridges-a total of six kinds of igniters( S,M,Lr,Lv,Hr,Hv) were tested by employing the Neyer D-optimal sensitivity method. The critical electro-exploding voltages of the igniters were explored. T...
