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.

Abdon: The main advantage of these devices is that you can still display a lot of complex information but without the need of any electronics.

So there’s been a switch to transitioning to more, um, analog physical encryption systems. In this project, we’re trying to reproduce some of the display functions that you see in the skin of squids.
