Guinness World Record smashed by QR code pixel just 50nm - 2500 sq nanometer size is smaller than COVID-19 virus, needs…
- Microscopic QR code measures just 50 by 50 nm² and is constructed using singular atoms of silver
- Researchers used quantum tunnelling techniques and automation to apply individual atoms to a mounting surface, with human intervention for fine adjustment
- The QR code is still scannable using a mobile phone despite being 800 times smaller than the current record holder
Researchers at the Monash University School of Physics and Astronomy and the Czech Academy of Sciences may have just shattered the Guinness World Record for smallest QR code, with their entry measuring almost 800 times smaller than the previous record.
Each individual pixel of the QR code is constructed using individual atoms of silver positioned using an ultra-precise scanning tunnelling microscope, meaning that the entire QR code is 1000 times smaller in width than a human hair.
Amazingly, as you will see below, the QR code is fully functional and can be...
