Three-dimensional trapping and assembly of small particles with synchronized spherical acoustical vortices
Zhixiong Gong, Michael Baudoin
Three-dimensional harmless contactless manipulation and assembly of micro-objects and micro-organisms would open new horizons in microrobotics and microbiology, e.g. for microsyste…
Acoustic radiation torque on a particle in a fluid: an angular spectrum based compact expression
Zhixiong Gong, Michael Baudoin
In this work, we derive a set of compact analytical formulas expressing the three-dimensional acoustic radiation torque (ART) exerted on a particle of arbitrary shape embedded in a…
Cell selective manipulation with single beam acoustical tweezers
Michael Baudoin, Jean-Louis Thomas, Roudy Al Sahely +7
Acoustical tweezers open major prospects in microbiology for cells and microorganisms contactless manipulation, organization and mechanical properties testing since they are biocom…
Particle assembly with synchronized acoustical tweezers
Zhixiong Gong, Michael Baudoin
The contactless selective manipulation of individual objects at the microscale is powerfully enabled by acoustical tweezers based on acoustical vortices [Baudoin et al., Sci. Adv.,…
Sound of Interfacial Flows: Unraveling the Forces Shaping Fast Capillary Flows using their Acoustic Signature
Adrien Bussonnière, Arnaud Antkowiak, François Ollivier +2
Many familiar events feature a distinctive sound: paper crumpling or tearing, squeaking doors, drumming rain or boiling water. Such characteristic sounds actually carry a profusion…
Folding a focalized acoustical vortex on a flat holographic transducer: miniaturized selective acoustical tweezers
Michaël Baudoin, Jean-Claude Gerbedoen, Olivier Matar +3
Acoustical tweezers based on focalized acoustical vortices hold the promise of precise contactless 3D manipulation of millimeter down to sub-micrometer particles, microorganisms an…
