Acoustic levitation is some day going to be used to brush the dust off machinery on Mars. Learn why sound can lift objects off the ground and see an acoustic levitation chamber in action. “Sticks and ...

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.

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...

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 ...

We may not have real hoverboards yet, but engineers have just invented a device that can levitate tiny objects using only the power of sound — a sonic tractor beam. Researchers say the technology ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

It may seem straight out of "Star Trek," but it's real: Scientists have created a sonic "tractor beam" that can pull, push and pirouette objects that levitate in thin air. The sonic tractor beam ...
