Abstract
Methods for fabricating dendritic structures and tags include introducing an electrolyte material onto a substrate, into a substrate, or both onto and into a substrate, and applying an electrical potential to at least one pair of electrodes positioned on the substrate to form one or more dendritic structures on the substrate.
Claims13
A method of forming dendritic structures, the method comprising:
- printing an electrically conductive ink on a substrate to form a multiplicity of pairs of electrodes on the substrate;
- curing the multiplicity of pairs of electrodes;
- immersing the substrate into an electrolytic solution;
- applying an electrical potential to the multiplicity of pairs of electrodes to form a multiplicity of dendritic structures on the substrate;
- passing the substrate through a rinse bath to remove excess electrolyte;
- passing the substrate through a fixing bath to chemically deactivate residual electrolyte material in or on the substrate;
- drying the multiplicity of dendritic structures;
- oxidizing the multiplicity of dendritic structures;
- applying a coating material to the multiplicity of dendritic structures;
- and
- cutting the substrate to yield a multiplicity of substrate pieces, each substrate piece comprising one or more of the multiplicity of dendritic structures.
