SOUND CARD

An international team produced a display that uses ultrasonic sound waves to alter film’s properties and create either a flat or a 3D image. The bubble mixture is more complex than the one sold in stores for children, but soap is still the main ingredient.

The team managed to control and exploit these properties by hitting the bubble’s membrane with ultrasonic sound waves, played through speakers.

Sonic waves alter the texture of a projected image, making it look smooth or rough.

Changing the wave’s frequency modifies the reflective property of the screen, meaning that the transparency of the projected image can also be changed.
