TipTrap: a co-located direct manipulation technique for acoustically levitated content
(ACM, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Acoustic levitation has emerged as a promising approach for mid-air displays, by using multiple levitated particles as 3D voxels, cloth and thread props, or high-speed tracer particles, under the promise of creating 3D ...
Nonlinear trapping stiffness of mid-air single-axis acoustic levitators
(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 ...
Enhancing the quality of amplitude patterns using time-multiplexed virtual acoustic fields
(American Institute of Physics, 2023)
Artículo / Artikulua,
Ultrasonic fields can push and levitate particles, heat up materials, induce contactless tactile stimuli, or affect the blood-brain barrier. Current phased-arrays can create dynamic amplitude patterns, but their quality ...
Optimization of acoustic fields: advances towards its use for matter manipulation and contactless fabrication
(2023)
info:eu-repo/semantics/doctoralThesis,
Los campos de presión acústica son capaces de modelar y levitar partículas de una amplia gama de materiales y tamaños a través del aire, el agua o el tejido biológico. Esto tiene aplicaciones en cristalografía, manipulación ...
Acoustic lock: position and orientation trapping of non-spherical sub-wavelength particles in mid-air using a single-axis acoustic levitator
(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 ...
Standing waves for acoustic levitation
(Springer, 2020)
info:eu-repo/semantics/bookPart,
Standing waves are the most popular method to achieve acoustic trapping. Particles with greater acoustic impedance than the propagation medium will be trapped at the pressure nodes of a standing wave. Acoustic trapping can ...
Acoustophoretic volumetric displays using a fast-moving levitated particle
(AIP Publishing, 2019)
info:eu-repo/semantics/article,
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° ...
Contactless pick-and-place of millimetric objects using inverted near-field acoustic levitation
(American Institute of Physics, 2020)
info:eu-repo/semantics/article,
We model and realize an ultrasonic contactless pick-and-place device capable of picking, self-centering, self-orienting, translating, and releasing flat millimetric objects. The device is an ultrasonic Langevin transducer ...
Acoustic levitation in mid-air: recent advances, challenges, and future perspectives
(American Institute of Physics, 2020)
info:eu-repo/semantics/article,
Mid-air acoustic levitation is becoming a powerful tool to suspend and manipulate millimetric objects. Because of its unique characteristics, acoustic levitation is suitable to trap a wide variety of materials such as ...
Numerical and experimental investigation of the stability of a drop in a single-axis acoustic levitator
(American Institute of Physics, 2019)
info:eu-repo/semantics/article,
Acoustic levitation can be employed to hold liquid drops in midair, enabling novel applications in X-ray scattering of proteins, amorphous crystallization of solutions, or contactless mixing. Multiple studies have characterized ...
