# Nanoscale QR Code Etchings TU Wien and Cerabyte Introduced a Microscopic QR Code By Debra John | Written with AI assistance | Published 2026-02-26 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/microscopic-qr-code References: [pcgamer](https://www.pcgamer.com/hardware/at-a-mere-2-square-micrometers-in-size-this-is-the-worlds-smallest-qr-code-and-its-smaller-than-most-bacteria/)  Researchers at TU Wien, working with Cerabyte, introduced a microscopic [QR code](https://www.trendhunter.com/trends/self-serve-QR) that covered just 1.98 square micrometers, featuring [pixels etched at 49 nanometers](https://www.trendhunter.com/trends/semiconductor-breakthrough) into a thin ceramic film. The team announced the result as a Guinness World Record and validated the code by imaging it with an electron microscope, then displaying that image for a conventional phone scan. The ceramic medium is noteworthy for its stability and potential longevity, designed to preserve information without continuous power or active cooling. The method mirrors archival approaches by encoding data into durable materials and could enable [ultra-dense, long-term physical storage](https://www.trendhunter.com/trends/mx-authenticity-check). For consumers and institutions, the work suggests future pathways for imperishable data tags and archival media, though practical scanning remains limited to electron microscopes today.
