Abstract
The disclosure features dendritic tags, and methods and systems for fabricating and using such tags. The methods can include obtaining at least one image of a dendritic tag attached to an article, analyzing the at least one image to identify a set of features associated with the dendritic tag, and comparing the set of features to stored information to identify the article.
Claims18
An article comprising:
- a paper substrate;
- and
- a dendritic structure grown on the paper substrate,
- wherein the dendritic structure comprises:
- at least one metallic material;
- and
- a plurality of members extending away from a common point of the dendritic structure to form a stochastically branched arrangement of the members, wherein regions of the dendritic structure are stochastically self-similar to the entire dendritic structure.

An article comprising:
- a substrate;
- and
- a dendritic structure electrodeposited on the substrate,
- wherein the dendritic structure comprises:
- at least one metallic material;
- and
- a plurality of members extending away from a common point of the dendritic structure to form a stochastically branched arrangement of the members, wherein regions of the dendritic structure are stochastically self-similar to the entire dendritic structure.
4 more elements
An article comprising:
- a single dendritic structure, wherein the dendritic structure comprises at least one metallic material;
- and
- a paper substrate supporting the single dendritic structure,
- wherein the single dendritic structure comprises a plurality of members extending away from a common point of the dendritic structure to form a stochastically branched arrangement of the members, and regions of the dendritic structure are stochastically self-similar to the entire dendritic structure.
