The Challenge

Counterfeiting is a major problem worldwide and costs companies and governments billions of dollars every year. Clothing, pharmaceutical drugs, electronics, and various other products require advanced security in order to protect from counterfeits.

Innovation Details

LumaChrome® is a color-shifting optical film for security labels that changes color when the viewing angle is changed. This allows the user to quickly authenticate a secure product. The labels are highly secure, durable, and easy to recognize at multiple angles and variable lighting conditions.

Biological Model

Blue morpho butterflies do not use to create the bright blue color on their wings. Instead, their wings have a layered microstructure that causes light waves that hit the surface of the wing to diffract and interfere with each other, so that certain color wavelengths cancel out while others, such as blue, are intensified and reflected.
