First acoustic metamaterial 'superlens' created

A team of researchers at the University of Illinois has created the world's first acoustic "superlens," an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural ...

Research brings 'smart hands' closer to reality

Using your skin as a touchscreen has been brought a step closer after UK scientists successfully created tactile sensations on the palm using ultrasound sent through the hand.

New "tricorder" technology might be able to "hear" tumors growing

When Dr. Leonard "Bones" McCoy needs to diagnose an ill member of the Starship Enterprise, he simply points his tricorder device at their body and it identifies their malady without probing or prodding. Similarly, when Capt. ...

Novel metamaterial vastly improves quality of ultrasound imaging

(PhysOrg.com) -- New "metamaterials" can overcome some of the limitations of microscopes and imagers, including ultrasound imagers. Researchers in the Nano-scale Science & Engineering Center have come up with a metamaterial ...

New technique allows ultrasound to penetrate bone, metal

Researchers from North Carolina State University have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called "aberrating ...

Sound bullets in water

Sound waves are commonly used in applications ranging from ultrasound imaging to hyperthermia therapy, in which high temperatures are induced, for example, in tumors to destroy them. In 2010, researchers at Caltech led by ...

Super-fine sound beam could one day be an invisible scalpel

A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound ...

Sensor predicts glass breakage

(PhysOrg.com) -- Modern glass fa├žades inform the architecture of major cities throughout the world. In recent years, however, there have been cases of broken glass, with collapsing facades endangering passers-by. Now, a ...
