British scientists presented new invention called the “tractor beam” that resembles something from Star Trek and can move and levitate objects by using sound waves.
The world’s first sonic beam can only move a tiny particle of less than one millimetres currently, but the team are now working on a machine that can lift a football.
Scientists from the Universities of Bristol and Sussex built a tractor beam that uses high-amplitude sound waves to create acoustic ‘tweezers’ which can pluck and shift objects.
The technique could be used to transport delicate objects and assemble them, without physical contact or transport drug capsules or microsurgical instruments through living tissue.
Asier Marzo, PhD student and the lead author, said: “It was an incredible experience the first time we saw the object held in place by the tractor beam. All my hard work has paid off, it’s brilliant.”
