Creating 3D objects with sound
Feb 2023, phys.org
Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed.They capture particles and cells freely floating in water and assemble them into three-dimensional shapes.The advantage of ultrasound is that it is gentle enough for using biological cells and that it can travel deep into tissue. This way it can be used to remotely manipulate and push cells without harm.

The first of its kind in the world, the project and its outputs not only enable the visual demonstration of the architecture of language, but also enables its preservation in a permanent, solid form.
