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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 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 ...
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° ...
LeviSense: a platform for the multisensory integration in levitating food and insights into its effect on flavour perception
(Elsevier, 2020)
info:eu-repo/semantics/article,
Eating is one of the most multisensory experiences in everyday life. All of our five senses (i.e. taste, smell, vision, hearing and touch) are involved, even if we are not aware of it. However, while multisensory integration ...
