Leviprint Making Objects through Acoustic Levitation

Acoustic levitation is the use of sound waves to levitate objects. In this video from CNET’s channel on YouTube, the host discusses LeviPrint, a device that uses acoustic levitation to manipulate small objects, like matchsticks, or matchstick-sized pieces of wood and pieces of glue to create a simple square and other simple shapes. He also talks to one of the researchers behind the technology, Asier Marzo, who explains some of the principles and possible applications. The device uses sound waves about twice the range of human hearing to accomplish its feats. These include passing objects through holes and manipulating them in totally enclosed spaces, such as a mesh bottle. Marzo explains that it could be useful for biomedical research where it would act against the problem of cross-contamination. However, it will be a long time before larger versions of the technology are available because this would require developing additional software and engineering to operate it.

I think the use of sound waves to levitate objects and manipulate them is absolutely amazing. It reminds me a little of a Marvel supervillain, whose body was made entirely of soundwaves created by a device replacing one of his hands. It also reminds me of the Farscape episode ‘Taking the Stone’, in which the crew of the Moya discovery a cemetery world, whose last inhabitants are hippy types, who use acoustic levitation as a form of skydiving. They jump into a long, subterranean shaft intoning a low sound as they go down. If they get it right, they are slowed and suspended before they hit the ground. If they don’t – splat! Farscape was broadcast about twenty or so years ago, which was when acoustic levitation was first discovered, I believe. It’s so weird and wonderful that I think our ancestors would have put it down to witchcraft and black magic. There are other videos on the Net discussing it, including one by a woman who built an acoustic levitation device herself.
