Acoustic Levitation uses the energy of sound to hold particles in mid-air without any physical contact. There will be live demonstrations and the audience will learn how to build their own levitators at home.
We will see that acoustic levitation is not suited for levitating humans but for accurately manipulating small particles, liquids or powder. Do not think about flying cars or humans but about tiny microbots inside your body that are controlled from the exterior, or levitated droplets of reagents in a complex chemical reaction.
During this talk, I will explain the working principles behind acoustic levitation, its applications and current challenges. Will this technology ever be transferred from research labs to industry? I am certain that a conversation with the public will produce novel applications and ideas.
If you want to make the levitator shown in the image above, follow this video and read the documents here: Instructions and supplies.
