Levitation has a way of arousing curiousity and wonder wherever it appears. There’s a multitude of ways to do it, each with their own strengths and weaknesses and ideal use cases. [Julius Kramer] ...

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 ...

Levitation techniques are no longer confined to the laboratory thanks to engineers who have developed an easier way for suspending matter in mid-air by developing a 3-D-printed acoustic levitator.

Using sound to get objects to float works well if a single particle is levitated, but it causes multiple particles to collapse into a clump in mid-air. Physicists at the Institute of Science and ...

The idea has been floated previously to use sound waves to make objects levitate. Research confirmed it, but as you may expect, this requires a direct path of waves to the object – interrupt them by ...

Finally our childhood dreams of a working tractor beam are coming to fruition! It’s called acoustic levitation and it actually uses highly concentrated sound waves to float small objects by ...

It’s possible to defy gravity using sound waves, magnets or electricity, but today’s methods can’t hoist heavy items high in ...

The bearings in your hard drive are critical to the performance and reliability of your PC and you rarely think about it as it runs silently in the background when you are surfing the Web, reading or ...

The Consumer Electronics Show (CES) started this week and has been dominating the news with revelations of gadgets that are exactly as irrelevant to you as they were last year and the year before and ...
