DRDO's exploding foil initiator or slapper detonators used in the firing mechanism of nuclear devices
Two types have been developed
1. Ceramic based
2. PCB based
The EFI detonator is similar to d design of an exploding bridge-wire in that a thin foil is exploded by the discharge

core in a simultaneous manner for supersonic compression along the geometric axis.
✍️Timing accuracies > 10 ns
✍️It is the shock from the polymer disc hitting the explosive that causes the detonator to function.
✍️Essential for SLBM due to the overriding safety factor.
