Functional coatings that change colour under mechanical, optical or electrical probing techniques can be used to generate practically unbreakable security features in next generation currencies, official documentation and high value goods.
Our easy to deposit materials can be applied via roll-to-roll processing. With laser pulses we are able to address our ultra-thin films at extremely high resolutions—just a few nanometers. This means we can create imagery and words beyond any resolutions that traditional printing industries are able to achieve. Laser writing like this is compatible with roll-to-roll processing meaning it could be deployed in high speed manufacturing.
