This cutting-edge research, <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/adma.202406149\" title=\"\">published<\/a> in Advanced Materials, promises new applications in areas such as clothing, ID badges and e-book readers where conventional light and power sources are impractical.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>&#8220;It&#8217;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,&#8221; Joerg Lahann, the Wolfgang Pauli Collegiate Professor of Chemical Engineering and co-corresponding author of the study, said in a <a href=\"https:\/\/news.umich.edu\/this-screen-stores-and-displays-encrypted-images-without-electronics\/\" title=\"\">news release<\/a>.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>The extraordinary screen can display a public image when near a standard magnet or reveal a private, encrypted image when placed over an intricate array of magnets acting as an encryption key. This innovation eliminates the risk of hacking associated with electronic codes and devices.<\/p>\n\n\n\n<p>&#8220;This device can be programmed to show specific information only when the right keys are provided. And there is no code or electronics to be hacked,&#8221; Abdon Pena-Francesch, an assistant professor of materials science and engineering at U-M and co-corresponding author, said in the news release. &#8220;This could also be used for color-changing surfaces, for example, on camouflaged robots.&#8221;<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Key to this technology is the way the screen&#8217;s &#8220;pixels,&#8221; tiny beads containing magnetic particles, flip between orange and white in response to magnetic fields. When exposed to a magnetic field, these beads change their orientation, creating the necessary color contrast to form an image. The screen&#8217;s magnetic properties make it act like an Etch-A-Sketch, erasing the display when shaken but allowing it to recreate the image under the influence of a magnetic field.<\/p>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"A screen using magnetic pixels stores and displays encrypted images without electronics\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/MjL3k8VaVnU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div style=\"height:11px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>The research team drew inspiration from nature, particularly from the color-changing capabilities of squids and octopi. <\/p>\n\n\n\n<p>&#8220;If you make the beads too small, the changes in color become too small to see,&#8221; added first author Zane Zhang, a U-M doctoral student in materials science and engineering. &#8220;The squid&#8217;s pigment sacs have optimized size and distribution to give high contrast, so we adapted our device&#8217;s pixels to match their size.&#8221;<\/p>\n\n\n\n<p>The polarization of the beads can be fine-tuned using different types of magnetic particles. For a single public image, multiple encrypted images can be revealed using unique magnetic keys, adding an additional layer of security.<\/p>\n\n\n\n<p>The researchers have submitted an invention disclosure for the device with the help of U-M Innovation Partnerships. The potential applications of this technology are vast, from secure information display to adaptable camouflage on robotics.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Engineers at the University of Michigan have unveiled a flexible screen inspired by squid, capable of storing and displaying encrypted images using magnetic fields instead of traditional electronics.
