For those that haven’t heard, ultrasonic levitation is a process by which two or more ultrasonic transducers are set opposite to each other and excited in such a way as to create a standing wave ...

[Mike] saw a few videos of ultrasonic acoustic levitation rigs put together by student researchers. Figuring it couldn’t be that hard to replicate, he set out and built his own using surplus parts and ...

Acoustic levitation conjures images of Star Trek­-style tractor beams and ultrasonic hover boards, but in reality floating objects on a cushion of sound occurs on far smaller scales. That’s in part ...

In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves ...

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 ...

A robot arm that can pick up and carry objects without touching them using ultrasonic levitation is being developed by scientists. Researchers at ETH Zurich used an array of tiny speakers that emit ...

Scientists have long dreamed of using acoustic levitation to float objects, but there has been one big catch: you couldn't lift an object larger than the wavelength without being picky about what ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Using ultrasound, a team of Japanese scientists has levitated small particles, and moved them around mid-air. It’s incredible to see. This isn’t the first time we’ve seen ultrasonic levitation, but it ...

Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.

Mexican researchers have used ultrasonic levitation to suspend droplets of water in the air and perform spectral analysis to detect contamination. Laser induced breakdown spectroscopy (LIBS) is ...
