The development in acoustic tractor beams comes from the University of Bristol. Acoustic tractor beams work on the basis of controlling sound in order to hold particles in mid-air. In a sense the beam ...

A study on the levitation technique titled "High-speed acoustic holography with arbitrary scattering objects" has been published in the journal Science Advances. Researchers from the University ...

Acoustic levitation employs high-frequency sound waves to suspend objects without physical contact, presenting a viable alternative to traditional mechanical handling methods. At its core, this ...

The average Hackaday reader is likely at least familiar with acoustic levitation — a technique by which carefully arranged ultrasonic transducers can be used to suspend an object in the air ...

Scientists from the University of Tokyo are bringing us a tiny bit closer to the dream of land speeders and hover boards, employing "acoustic levitation" to make objects move in unprecedented ways.

One day soon, we may get to see the flying cars we were promised as citizens of the 21st century. Swiss researchers have figured out how to levitate objects and particles in mid-air—they can even move ...
