Acoustic lock: position and orientation trapping of non-spherical sub-wavelength particles in mid-air using a single-axis acoustic levitator
Cox, L; Croxford, A; Drinkwater, Bruce W.; Marzo Pérez, Asier
(American Institute of Physics, 2018)
Artículo / Artikulua 
We demonstrate acoustic trapping in both position and orientation of a non-spherical particle of sub-wavelength size in mid-air. To do so, we multiplex in time a pseudo-one-dimensional vertical standing wave and a ... -
Acoustic virtual vortices with tunable orbital angular momentum for trapping of Mie particles
Marzo Pérez, Asier ; Caleap, Mihai; Drinkwater, Bruce W. (American Physical Society, 2018)
Artículo / Artikulua
Acoustic vortices can transfer angular momentum and trap particles. Here, we show that particles trapped in airborne acoustic vortices orbit at high speeds, leading to dynamic instability and ejection. We demonstrate stable ... -
Acoustophoretic volumetric displays using a fast-moving levitated particle
Fushimi, Tatsuki; Marzo Pérez, Asier ; Drinkwater, Bruce W.; Hill, Thomas L. (AIP Publishing, 2019)
Artículo / Artikulua
Displays have revolutionized the way we work and learn, and thus, the development of display technologies is of paramount importance. The possibility of a free-space display in which 3D graphics can be viewed from 360° ... -
Holographic acoustic elements for manipulation of levitated objects
Marzo Pérez, Asier ; Seah, Sue Ann; Drinkwater, Bruce W.; Sahoo, Deepak Ranjan; Long, Benjamin; Subramanian, Sriram (Nature Publishing Group, 2015)
Artículo / Artikulua
Sound can levitate objects of different sizes and materials through air, water and tissue. This allows us to manipulate cells, liquids, compounds or living things without touching or contaminating them. However, acoustic ... -
Holographic acoustic tweezers
Marzo Pérez, Asier ; Drinkwater, Bruce W. (National Academy of Sciences, 2019)
Artículo / Artikulua
Acoustic tweezers use sound radiation forces to manipulate matter without contact. They provide unique characteristics compared with the more established optical tweezers, such as higher trapping forces per unit input power ... -
Nonlinear trapping stiffness of mid-air single-axis acoustic levitators
Fushimi, Tatsuki; Hill, Thomas L.; Marzo Pérez, Asier ; Drinkwater, Bruce W. (American Institute of Physics, 2018)
Artículo / Artikulua
We describe and experimentally explore a nonlinear stiffness model of the trapping of a solid particle in a single-axis acoustic levitator. In contrast to the commonly employed linear stiffness assumption, our nonlinear ...
