- Researchers from TU Wien created a QR code smaller than a human hair's width
- The microscopic QR code measures only 1.977 square micrometers in size
- It was made by cutting chromium nitride thin film with a focused ion beam
In a remarkable scientific achievement, researchers have created an extremely tiny QR code, showing how far technology has advanced at the microscopic level.
Researchers from TU Wien in Austria have created a QR code that is smaller than the width of a human hair, setting a new benchmark in miniaturisation.
The QR code was prepared by cutting a thin layer of chromium nitride with the help of a focused ion beam. Its size is only 1.977 square micrometers, making it among the smallest QR codes of its kind.
