Scientists at the University of Tokyo and the Nagoya Institute of Technology were recently able to levitate small items in three dimensions using only sound waves. While it's not uncommon for ...

The sound intensity determines the maximum density of an object that can be pushed and pulled by the acoustic force, Drinkwater said. In this instance, the sound waves operate between 140 and 150 ...

"No eye-wear or tricks required, simply 3D shapes sharing the very space in which we live." Levitating Researchers have come up with a new and improved way to levitate objects using sound waves ...

We may not have real hoverboards yet, but engineers have just invented a device that can levitate tiny objects using only the power of sound — a sonic tractor beam. Researchers say the ...

An advanced "sound tweezer" can manipulate dozens of objects independently using hundreds of tiny speakers, allowing for noninvasive surgery and a new, highly interactive type of 3D display.
