Abstract
An apparatus with an anti-tamper architecture includes a substrate and a layer of a pyrotechnic composite arranged on a surface of the substrate. The pyrotechnic composite includes a metal and a metal oxide, and the layer has a thickness of about 1 micrometer to about 10 millimeters. A reaction of the pyrotechnic composite is an exothermic reaction and at least partially fractures the substrate after the reaction is initiated.
Claims20
An apparatus with an anti-tamper architecture comprising:
- a substrate;
- and
- a layer of a pyrotechnic composite arranged on a surface of the substrate, the pyrotechnic composite comprising a metal and a metal oxide, and the layer having a thickness of about 1 micrometer to about 10 millimeters;
- wherein a reaction of the pyrotechnic composite is an exothermic reaction and at least partially fractures the substrate after the reaction is initiated.
A method for forming an anti-tamper feature on an apparatus, the method comprising:
- depositing, by an additive manufacturing method, a layer of an energetic material on a surface of a substrate, the layer having a thickness of about 1 micrometer to about 10 millimeters;
- wherein a reaction of the energetic material is exothermic and at least partially fractures the substrate after the reaction is initiated.
A method for at least partially fracturing an apparatus with an anti-tamper feature, the method comprising:
- initiating a reaction of a layer of an energetic material arranged on a surface of a substrate, the energetic material comprising metal and a metal oxide, and the layer having a thickness of about 1 micrometer to about 10 millimeters;
- wherein the reaction of the energetic material is exothermic and at least partially fractures the substrate after the reaction is initiated.
