The need for the accurate generation of acoustic holograms has increased with the
prevalence of the use of acoustophoresis methods such as ultrasonic haptic sensation …

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 …

We present a simple dynamic model for predicting the manipulation behavior of an
acoustically levitated sphere. The model allows for the calculation of the sphere position …

Air-coupled ultrasonic phased arrays are utilized for many emerging applications and
typically consist of bending-plate piezoelectric ultrasonic transducers (PUT). Due to their …

We propose a method for two-dimensional remote position control of centimeter-scale
objects using airborne ultrasound. To actuate objects 1–2 cm in size, previous studies …
