A collaborative effort between a team from the Vienna University of Technology and Cerabyte has culminated in the successful creation of a QR code that occupies a minuscule area of just 1.98 square micrometers, setting a fresh benchmark in the Guinness World Records. This groundbreaking technology involves engraving the QR code onto an ultra-thin ceramic film, where each pixel is a mere 49 nanometers in size—far too small to be discerned by the naked eye, yet perfectly readable under an electron microscope. Ceramic storage offers an impressive data density, with storage carriers that can endure almost indefinitely without the need for continuous power supply, presenting vast opportunities in the realm of long-term data preservation. Presently, the research team is delving into alternative materials, accelerating write speeds, and refining manufacturing techniques to propel the industrial adoption of ceramic data storage, as well as delving into the intricacies of encoding more complex data structures.
