Engineers create squid-inspired magnetic screen for encrypted displays
Researchers have developed a flexible, magnet-based screen inspired by squid, capable of storing and displaying encrypted images.
A team at the University of Michigan claims its screen is versatile for applications where light and power sources are impractical, such as in clothing, stickers, ID badges, barcodes, and e-book readers. And unlike some earlier mechanical computers, this device can wrap around your wrist,” said Joerg Lahann, professor of chemical engineering at the University and co-corresponding author of the study, in a statement. Nonetheless, private images can be exhibited with a second magnetic grid that selectively modifies how some regions of the screen flip since iron oxide particles can be reprogrammed with comparatively weaker fields.
