Abstract
Microstructured taggant particles, their applications and methods of making the same are described. Precisely formed taggant particles can be formed, in the range of 500μ and smaller, from either inert polymers or biodegradable materials bearing information indicia, such as through specific shape, size, color, reflectivity, refractive index, surface geometry, imprinting, optical effect or properties, and electromagnetic properties, to uniquely tag, identify or authenticate articles.
Claims9
A taggant particle having identifying indicia, wherein the identifying indicia comprises a design imparted onto or into the surface of the taggant particle wherein said design is a metallized pattern engineered to have a specific electrical or electromagnetic impedance.
A metallized taggant particle of about 500 microns or less, the taggant particle being formed into a shape selected to provide a specific impedance to operate as an antenna.
