Abstract:
An electro-explosive device fabricated on the surface of a substrate, the electro-explosive device comprising:(a) a laminate layer deposited on the surface of the substrate, the laminate layer comprising a series of alternating layers of a reactive metal and a reactive insulator, the reactive insulator having a resistivity that is high relative to the resistivity of the reactive metal, the laminate layer being configured to define a bridge joining two relatively large sections, (b) comprising, (i) two relatively large sections that substantially cover the surface area of the substrate; and (ii) bridge section joining the two relatively large sections; and (c) a conductive contact pad coupled to each of the at least one of the series of alternating layers, wherein a predetermined current through the at least one conductive contact pad causes the bridge section to initiate a reaction in which the laminate layer is involved.
