Research advances of acoustic particle manipulation techniques in field-assisted manufacturing

Field-assisted manufacturing (FAM) technology, which employs external fields to transport and manipulate micro/nanoparticles for tailored arrangements and structures, can produce novel materials with specific properties and functions. Acoustic particle manipulation has attracted increasing attention in FAM due to its various advantages, such as a wide range of materials, ease of fabrication, rapid actuation, non-invasive operation and high biocompatibility. The present review summarizes the recent progress of acoustic particle manipulation in the FAM area, with respect to operation principles, fabrication and control of particles, and particle cluster patterning. The emphasis is placed on the recent innovative applications of microparticle manipulation realized by acoustic fields in different advanced manufacturing technologies. Finally, we provide our perspective on the current challenges and potential prospects of acoustic particle manipulation technology in FAM.
