The levitation of small living animals has also been studied and the vitality of animals which typically exist in air was not affected.<ref name="Xie 214102"/> In future it could be used as a tool to study the animals themselves.
 
There wasis also beenactive research in the field of contactless assembly. The levitation of [[Surface-mount technology|surface mount]] electrical components has been demonstrated<ref name=":2" /><ref name=":3" /> as has micro-assembly with a combination of acoustic and magnetic fields.<ref>{{Cite journal|last1=Youssefi|first1=Omid|last2=Diller|first2=Eric|date=April 2019|title=Contactless Robotic Micromanipulation in Air Using a Magneto-Acoustic System|journal=IEEE Robotics and Automation Letters|volume=4|issue=2|pages=1580–1586|doi=10.1109/LRA.2019.2896444|s2cid=67872033|issn=2377-3766}}</ref> There is also commercial interest in 3D printing whilst levitated, with [[Boeing]] filing a patent on the concept.<ref>{{Cite patent|title=Free-Form Spatial 3-D Printing Using Part Levitation|gdate=2014-07-29|url=https://patents.google.com/patent/US20160031156A1/en}}</ref>
 
Acoustic levitation has also been proposed as a technique for creating a [[volumetric display]], with light projected onto a particle, which moves along the path to create the image faster than the eye can process. This has already proved possible<ref>{{Cite journal|last1=Fushimi|first1=Tatsuki|last2=Marzo|first2=Asier|last3=Drinkwater|first3=Bruce W.|last4=Hill|first4=Thomas L.|date=2019-08-05|title=Acoustophoretic volumetric displays using a fast-moving levitated particle|journal=Applied Physics Letters|volume=115|issue=6|pages=064101|doi=10.1063/1.5113467|bibcode=2019ApPhL.115f4101F|hdl=2454/36412|issn=0003-6951|url=https://research-information.bris.ac.uk/ws/files/204902388/Acoustophoretic_Volumetric_Displays_using_a_Fast_Moving_Levitated_Particle.pdf}}</ref> and has been brought together with audio and haptic feedback from the same PAT.<ref>{{Cite journal|last1=Hirayama|first1=Ryuji|last2=Martinez Plasencia|first2=Diego|last3=Masuda|first3=Nobuyuki|last4=Subramanian|first4=Sriram|date=November 2019|title=A volumetric display for visual, tactile and audio presentation using acoustic trapping|url=https://www.nature.com/articles/s41586-019-1739-5|journal=Nature|language=en|volume=575|issue=7782|pages=320–323|doi=10.1038/s41586-019-1739-5|pmid=31723288|bibcode=2019Natur.575..320H|s2cid=207986492|issn=1476-4687}}</ref>
