It uses magnetic fields to display images at the same resolution as a squid’s color-changing skin.

A flexible screen inspired, in part, by squid can store and display encrypted images like a computer—using magnetic fields rather than electronics. The research is reported today in Advanced Materials by University of Michigan engineers.
“It’s one of the first times where mechanical materials use magnetic fields for system-level encryption, information processing and computing. And unlike some earlier mechanical computers, this device can wrap around your wrist,” said Joerg Lahann, the Wolfgang Pauli Collegiate Professor of Chemical Engineering and co-corresponding author of the study.
