LEVITATION POSSIBLE BY USING SOUND WAVES

 

 

Scientists prove it is possible to levitate

and move objects in mid air using only sound

 

THE TELEGRAPH - Imagine how much easier life would be if it was possible to levitate objects. Maglev trains, for example, use powerful magnets to repel the carriages and remove the friction of the train on the tracks.

 

But magnets are just one way of achieving this – and they require the object to have a repelling magnetic force. Now scientists in Japan have shown that a similar effect can be achieved with sound. 

In this video they show that it is not only possible to levitate objects in mid-air using sound waves, but also to move them around. The results can be quite artistic – look about 1 minute in to see just what is possible.

 

They then levitate match heads, drops of water, screws and nuts.

 

The researchers at the University of Tokyo say they hope to refine the technique so it can be used to manipulate delicate electronic components when assembling hardware.

Researchers develop way to levitate objects
 in 3D space by using sound.

 

Could hoverboards (like the one used by Marty McFly in a Back to the Future sequel) be closer than we think?

 

 

HOW DO THE OBJECTS FLY?

 

DAILY MAIL - A machine uses speakers that produce sound at high frequencies inaudible to the human ear to generate sound waves that intersect.

 

They create a 'moveable ultrasonic focal point' or cross-over of high frequency noise made up of standing waves.

 

The waves, which remain in a constant position, provide a suspending force so that the focal point or cross-over can support a small floating object trapped in the standing waves.

 

Particles, a screw, 3mm piece of wood, water droplets and a soap bubble have been manipulated in mid air using acoustic levitation.
