Sonic screwdriver and force fields

Source

The technology is already being trialled in modern manufacturing to fix parts together and ultrasonic force fields are being developed within the medical field to separate diseased cells from healthy cells. Professor Drinkwater and The Big Bang team are now exploring whether super powerful versions of these sound beams could bring Doctor Who's iconic device to life.

Aaaaah... The magic of the right wavelength... Imagine the manufacturing plant of the future where you would see products seemingly assemble themselves.

Engineers are looking into how ultrasonic waves can be spun at high speed to create a twisting force similar to that of a miniature tornado, which could undo screws remotely. They have also experimented with rotating ultrasonic force fields which would act like the head of a real screwdriver.
