Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug ...

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 ...

In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

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.

Levitation may sound like magic, but there are a wide variety of physical phenomena that can be manipulated to generate the desired effect. In this case, [Mirko Pavleski] has built a rig capable of ...

There are few things cooler than the way in which scientists are able to get objects to levitate above the ground. But while many of the recent levitating technologies we’ve seen involve ...

In the perhaps not so distant future, surgeons could perform a range of medical procedures all without touching the patient, thanks to advancements in 'acoustic tweezers'. Surgeons won't be shrunk and ...

STORY: A UK startup is using soundwaves to make objects levitate in midair. And London-based AcoustoFab says it's "acoustic levitation" is not just a neat trick. It could also have commercial ...

In 2018 we have almost become jaded by levitating objects. You name it and there's probably a levitating iteration on the market: turntables, Bluetooth speakers, cameras, lightbulbs, clocks, and even ...

What does the future of construction look like? Autonomous machines buzzing around a building site? Giant 3D printers extruding walls and floors? Looking forward even farther, researchers at the ...

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 ...
