Researchers Set World Record By Creating QR Code Thinner Than Human Hair

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.
