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] ...
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 ...
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 ...
Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and ...
Levitation is no longer just the realm of magicians, with engineers dabbling in ways to suspend objects in midair using magnets, heat flow or sound waves. Unfortunately, it usually only works with ...
Acoustic levitation of a polystyrene sphere, the first spherical object to be acoustically levitated that is larger than the acoustic wavelength. Credit: Andrade et al. ©2016 AIP Publishing When ...
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 ...
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 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 ...
