Novel Nano-imprinting Technology for Anti-counterfeiting Micro-images and Information Storage

This novel nano-imprinting technology creates micro-images on high valuable products for anti-counterfeiting and information storage. Each pixel in the micro-image is encoded by adjusting its direction, allowing a massive amount information to be stored inside. In this way, a string of anti-counterfeiting code can be digitally encoded into the micro-image. The micro-image cannot be replicated without knowing the code, so that this technology is more effective in preventing counterfeiting in comparison to traditional image anti-counterfeiting methods.

The technology combines precision motion control technology and piezoelectric drive technology to achieve high-precision machining of micro/nanoscale structures. This enables it to create micro-images and QR codes on various industrial materials. Given its wide range of applications, this technology is expected to revolutionise existing image anti-counterfeiting technology and extend its use to protect valuable products and store important information.
