Acoustic levitators are becoming increasingly common research instrumentation for contact-
free, lab-in-a-droplet studies. Recently, levitators that employ multiple, small, ultrasonic …

Hypothesis Acoustic levitation provides the possibility to deform levitated droplets in a
controllable, and quantifiable manner, thus offering a means to measure the surface tension …

Recently, acoustic levitation of a wavelength-sized spherical object using a general-purpose
ultrasonic transducer array was demonstrated. In this article, the possibility of extending the …

Acoustic levitation is considered one of the most effective noncontact particle manipulation
methods, along with aerodynamic, ferromagnetic, and optical levitation techniques. It is not …

Damage-prone microscale products that need to be mass-assembled, such as surface
mount devices, would benefit from being assembled in mid-air using acoustic forces. These …

Acoustic levitation of spherical objects in mid-air is a technique that is gaining traction in
various human computer interaction applications such as data visualization or interactive …

Levitating particle displays are an emerging technology where content is composed of
physical pixels. Unlike digital displays, manipulating the content is not straightforward …

We propose a method to generate an acoustical levitation trap at the same time as
suppressing the sound in a multi-wavelength region of space. The method uses a spherical …
