Researchers Build A Real-Life 'Star Trek' Tractor Beam - In Miniature
In Star Trek, the team of the USS Enterprise use a fixated beam of graviton to seizure and transport passing objects in space.
For their actual tractor beam, the scientists used a collection of 64 speakers to generate the high-intensity sound waves which basically produces a force field around an object like a plastic bead.
By sensibly directing the output of the speakers, the bead can be elevated, held stationary, stirred and also revolved.
Researchers were also able to move several small beads at once.
Unlike earlier efforts to use sound in this way, the object does not need to be bounded by speakers at all.
As an alternative by focusing the sound at different points, it is likely to make the acoustic hologram from a smooth arrangement of speakers.
Professor Bruce Drinkwater, an ultrasonics researcher at the University of Bristol, added: 'We all know that sound waves can have a physical effect.
But here we have managed to control the sound to a degree never previously achieved.'
Tractor beam can invisibly ensnare and levitate objects
