- Austria-based researchers created the smallest QR code, requiring an electron microscope to view.
- The QR code measures 1.98 square micrometers, smaller than many bacteria, earning a Guinness World Record.
- Previous record was 5.38 square micrometers by a German team, but durability was a challenge.
- The team used ceramic film for stability, with pixels just 49 nanometers each, invisible to visible light.
- An A4-sized ceramic film could hold over 2 TB of data, advancing high-density storage solutions.
- Future research includes exploring other data structures and materials for long-term, energy-efficient storage.
- Ceramic tech competes with DNA storage, magnetic molecules, and Microsoft's laser-etched glass.
