Scientists have been able to use the power of sound to levitate small items — including insects and fish — for decades. But now researchers from Switzerland have figured out how to move objects around ...

Levitation is often thought of as the realm of magicians or The Jetsons, but it is technically possible. That said, the tech seems to be moving pretty slowly. Now, researchers at the University of ...

Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...

Researchers have built a levitation device to help them make precise measurements of chemical reactions (Anal. Chem. 2020, DOI: 10.1021/acs.analchem.0c00929). Levitating droplets on sound waves allows ...

In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...
