Detecting counterfeit electronics

Not only drugs are counterfeited (see article on Sproxil) but increasingly there is a world trade in counterfeit electronics–old, substandard components are remanufactured to appear new and brand-name. For mission-critical functions–or in health tech–this can mean bad readings, hazard or failure. Initial research from the US Army Research Laboratory (ARL) Army Research Office (ARO) on a DNA tag was developed with a private company, ChromoLogic LLC, which first developed a tag with a biomimetic barcode that can be aligned in the proper order and decoded by an optical reader–and the technology was extended to optical mapping of electronic components’ intrinsic surface or ‘fingerprinting’ by their DTEK system. The rather circuitous story is here in this strangely titled Armed With Science article, Sneaky Discovery Can Identify Counterfeits, Track Materiel
