Polymer particles hung in the air under the influence of sound waves.
Researchers from the University of Glasgow has achieved levitation – they managed to suspend the polystyrene particles in the air using only ultrasonic acoustic waves.
Once advanced technology is going to revolutionize the way people interact with each other, cars or any material. For example, the data can look like literal physical levitating objects that fly us in the air. There is also the desire to these objects it was possible to gently manipulate the intuitive gestures that would facilitate their use.
As explained by Stephen Brewster, Professor of human interaction with the computer in the University: “for Example, when working on a car model I could create this model in front of me, spacing in space of the surface of the car.”
Smart device can also be programmed in the case of this technological breakthrough. A simple gesture of a finger in the air can control the music player with programmed levitating “play”button.
This discovery is still actively being studied to understand how it can be applied in the real world.
Flights of fancy? Not quite, say physics.
This is not the first time that scientists use the theory of levitation. Theoretical physicists from the University of St Andrews were able to raise tiny objects back in 2007 – but only in theory. The hypothesis was made after scientists agreed that levitation can be a result of changes in the Casimir effect.
The Casimir effect, explained simply, is that objects are attracted to each other. That’s what makes them “stick together” quantum force. Investigating this phenomenon, scientists believe that theoretically, the objects can levitate.
Working with this theory, Professor Ulf Leonhardt and Dr Thomas Philbin of the University school of physics and astronomy began to calculate and develop the type of lenses which could negate the effect of “dry glue” that molecules exert on each other.
Both physics are unable to create a real technology that has reached their goal. However, they wrote that their theory would have radical consequences in the field of nanotechnology. If scientists could find a way to make objects float, manipulating quantum physics, they could create electrical circuits and mechanical devices working in all types of environment.
Professor Leonhardt explained, “the Casimir Force is the main cause of friction in the nanoworld, in particular in some microelectromechanical systems. Micro or nano machines could run smoother and with less friction or no friction, if you can manage this power.”
Engineers at mit were so fascinated by this idea that he decided to try his hand at levitation of the object, although this time they used electromagnetic principles. Their “Levitron” was able to hang the object in the air, combining magnetic repulsion and gyroscopic effect of the spinning top.
These designs showed the effectiveness on paper, but researchers have not yet developed a device that could really make something levitate.
However, who knows, maybe this fantastic dream will become a reality soon?
