In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...

A team of researchers at University College London has developed a way to keep objects levitated by sound waves airborne when other objects interfere with the levitation path. In their paper published ...

Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials. The ability to move objects without touching them might ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array ...
