Metamaterials
-
Researchers at the University of Sussex have developed SoundBender, a technology that bends sound waves around obstacles to acoustically levitate objects above them.
-
Metamaterials that cloak people and objects from radar, visible light or infrared are usually thick and heavy, but now engineers at the University of Wisconsin-Madison have developed an ultrathin, lightweight sheet that absorbs heat signatures and can even present false ones.
-
Researchers have developed a new technique to make metamaterials with nanoscale structures that can be tuned with strange optical properties. Using DNA-modified gold nanoparticles, the team could change the material's color, opening the door for new sensors or cloaking devices.
-
Researchers have invented a material that can bend, shape and focus sounds that pass through it, creating new possibilities for medical imaging, personal audio and other acoustic devices. The precisely engineered surface is a metamaterial, a new class of materials that seem to do the impossible.
-
Rubber and steel are at different ends of the spectrum of hardness, and wherever an object falls on that scale is typically where it will stay. But now, researchers have developed a metamaterial that can change the stiffness of its surface, from hard to soft and back.
-
Harvard researchers have come up with a toolkit for constructing metamaterials that flow from one shape and function into another, like very impressive origami.
-
ScienceResearchers at the University of Utah have devised a method to create invisible images embedded within normal-looking images using cheap inkjet printers. The data hidden in these images can then only be revealed using sub-millimeter electromagnetic radiation
-
Researchers at the University of California San Diego claim to have created the world's first microelectronic device that has no semiconductors, instead employing low-power laser optical control to increase its conductivity by more than 1,000 percent.
-
The tools to overcome problems with wireless charging already exist, according to a new paper that outlines how an LCD-like panel could be used to charge several devices simultaneously from a distance of up to 33 feet.
-
ScienceIt's one of the basic facts of science: Heat something and it expands. But a team of scientists from LLNL have gone counterintuitive and invented a 3D-printed material that shrinks when heated.
-
ScienceResearchers have developed a lens that operates at terahertz frequencies that are not only simple and inexpensive, but are claimed to produce near-flawless images which could vastly improve biomedical imaging as well as biological and explosive security scanning.
-
Engineers at Iowa State University may have gotten one step closer to the ability to make objects invisible with the development of what they are calling a flexible, stretchable and tunable meta-skin that can suppress radar detection.
