Newly-developed acoustic technologies used to move particles and create haptic feedback in mid-air have stirred the imagination of many researchers. Unfortunately, the complexity of the equipment required to perform these functions has meant that air-shaping technology has been somewhat expensive and difficult. Now researchers in Germany have created a simple system that uses printed plastic templates and ultrasonics to move and manipulate particles using holograms made of sound.
