Researchers recently created an acoustic hologram, or a 3D sound field projected onto a 2D space, which can be used as acoustic tweezers, cages and twisters that manipulate objects as they levitate in ...

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.

Along with personal jetpacks for every man, woman, and child (sure, why not), levitation is one of those conveniences that sci-fi has long promised us but has yet to deliver, other than magnetically ...

Development for the tire industry has focused on minimizing friction between car and road. The key to high-speed concepts such as Hyperloop, is the elimination of friction in transportation. Which is ...

TORONTO (CTV Network) — Researchers at Tokyo Metropolitan University have created ‘tweezers of sound’ that can move objects without physical contact. The technology creates non-contact manipulation of ...

The researchers were able to levitate and transport items ranging from a droplet of water to a toothpick. They did so using pairs of sound-emitting platforms and reflector sheets. Sound leaves the ...

Scientists have been able to use the power of sound to levitate small items — including insects and fish — for decades. But now researchers from Switzerland have figured out how to move objects around ...

Water droplets, coffee granules, fragments of polystyrene and even a toothpick are among the items that have been flying around in a Swiss laboratory lately — all of them kept in the air by sound ...

Although movie and game producers can now create computer-animated images of just about anything, the sounds made by those onscreen items still typically consist of recordings of real-world objects.
