Breathing Down the Necks of Counterfeiters
A technology developed by a team at the University of Michigan, along with research partners in South Korea, has used polyurethane as part of a label that cannot be easily copied.
An array of tiny pillars on the top of a surface — comparable to a sub-microscopic toothbrush, says the team — hides the image beneath. When moisture from a breath gets between the minute polyurethane pillars, the image is revealed.
These labels could be produced and inserted into a variety of consumer goods and packaging including, pharmaceuticals, clothes, sneakers, and handbags. The durability of polyurethane ensures that the labels and the images they hide will outlast a counterfeiter’s plan.
