Acoustic levitation permits non-contact handling of mm-scale samples. To improve its applicability, we did a simulation study to optimize orientation control of a sample residing in a phased array levitator. The acoustic forces and torques on asymmetric samples in asymmetric traps were determined by solving the acoustic scattering problem with the boundary element method. The angular stiffness of the trap was mapped as a function of the field shape. This allowed us to choose the optimal…

Multifrequency Acoustic Levitation

Acoustic levitation permits non-contact particle manipulation. The position and orientation of the levitated particle can be controlled by altering the acoustic field. Existing acoustic levitators…

BEM-FEM Simulation of Acoustic Levitation Dynamics with Phased Arrays

We present a simulation model that can be used to study the movement of an object in an acoustic levitator. The model uses the boundary element method (BEM) to compute the levitator's acoustic field,…

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…

Holographic acoustic elements for manipulation of levitated objects

The phases used to drive an ultrasonic phased array are optimized and it is shown that acoustic levitation can be employed to translate, rotate and manipulate particles using even a single-sided emitter.
