Doctor Who's famous object manipulating 'Sonic Screwdriver' has come a step closer to reality.
Scientists at the University of Dundee have created an ultrasound-powered machine which can lift, spin and manipulate objects using sound alone.
The device echoes Dr Who's multi-purpose device - which the doctor uses as a lock pick, a medical scanner and even a weapon.
Matt Smith as Dr Who demonstrates the sonic screwdriver. Now scientists at Dundee University have created a similar device
The team said the beam carries momentum that can push an object in its path and can cause the object to rotate when shaped like a helix or vortex
Physicists at the University of Dundee used equipment designed for MRI-guided ultrasound surgery and created a tool that can lift and spin a 10cm rubber disk with an ultrasound beam.
The team said the beam carries momentum that can push an object in its path and can cause the object to rotate when shaped like a helix or vortex.
Mike MacDonald, of the university's Institute for Medical Science and Technology, said: ‘This experiment not only confirms a fundamental physics theory but also demonstrates a new level of control over ultrasound beams which can also be applied to non-invasive ultrasound surgery, targeted drug delivery and ultrasonic manipulation of cells.
