Abstract:
A method and circuit for implementing transient electronic circuits for security applications, and a design structure on which the subject circuit resides are provided. Silver nanowire traces are fabricated forming a protection circuit in a soluble material. A frangible material is provided separating the soluble material from a solvent layer proximately located. During a tampering event the frangible material is ruptured releasing the solvent which contacts and dissolves the soluble material and disperses the silver nanowire traces creating an electrical open in the protection circuit. The electrical open enables enhanced tampering detection.

Claim (Index 1):
A circuit for implementing enhanced tampering detection for security applications comprising:\n silver nanowire traces fabricated in a soluble material forming a silver nanowire layer of a protection circuit; said silver nanowire layer carried by a security surface for one of the security applications; electrical connections attached to the silver nanowire layer used for electrical open measurements; a frangible material separating the soluble material from at least one solvent layer proximately located to said silver nanowire layer; said frangible material defining a frangible layer containing said at least one solvent layer; said frangible material layer being ruptured responsive to an applied force by attempts at physical access to the protection circuit, releasing the solvent material of said at least one solvent layer, which contacts and dissolves the soluble material and disperses the silver nanowire traces creating an electrical open in said silver nanowire layer of the protection circuit, said electrical open between said electrical connections provided to the protection circuit enabling enhanced tampering detection.
