Acoustic levitation in mid-air: recent advances, challenges, and future perspectives
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 ... -
Acoustic lock: position and orientation trapping of non-spherical sub-wavelength particles in mid-air using a single-axis acoustic levitator
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
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
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 ... -
Enhancing the quality of amplitude patterns using time-multiplexed virtual acoustic fields
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 ... -
LeviPrint: contactless additive manufacturing using acoustic levitation with position and orientation control of elongated parts
LeviPrint assembles small objects in a contactless way using ultrasonic phased-arrays and optimization algorithms. We explore a set of methods that enables 6 Degrees-of-Freedom (DoF) control of elongated bodies. We then ... -
LeviSense: a platform for the multisensory integration in levitating food and insights into its effect on flavour perception
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 ... -
Nonlinear trapping stiffness of mid-air single-axis acoustic levitators
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 ... -
Numerical and experimental investigation of the stability of a drop in a single-axis acoustic levitator
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 ... -
Optimization of acoustic fields: advances towards its use for matter manipulation and contactless fabrication
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 ... -
Standing waves for acoustic levitation
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 ... -
TipTrap: a co-located direct manipulation technique for acoustically levitated content
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 ...
