Abstract:
An electro-explosive device fabricated on the surface of a substrate, said electro-explosive device comprising:a layer of conducting material deposited on said surface of said substrate, said layer of conducting material being configured to define a bridge on said substrate for vaporizing in a plasma in response to the flow of electric current through said bridge;a composite overcoat formed on said bridge and bonded with said layer of conducting material of said bridge, said composite overcoat comprising a metal and an oxidizer, wherein said metal and said oxidizer are deposited to form separate layers of metal and oxidizer bonded with said layer of conducting material of said bridge; andmeans for coupling said bridge to a source of firing potential for inducing current flow through the bridge to cause an explosion of said composite overcoat for igniting a pyrotechnic mix disposed adjacent said electro-explosive device.
