Mid-air haptic feedback presents exciting new opportunities for useful and delightful
interactive systems. However, with these opportunities come several design challenges that …

LeviPrint is a system for assembling objects in a contactless manner using acoustic
levitation. We explore a set of optimum acoustic fields that enables full trap** in position …

Sparse spiral phased arrays are advantageous for many emerging air-coupled ultrasonic
applications, since grating lobes are prevented without being constrained to the half …

Acoustic levitation has recently demonstrated the ability to create volumetric content by
trap** and quickly moving particles along reference paths to reveal shapes in mid-air …

Encrypted acoustic meta‐holograms have potential applications in confidential acoustic
information communication, noise control, acoustic cloaking, acoustic illusion, etc …

Phased arrays of transducers have been quickly evolving in terms of software and hardware
with applications in haptics (acoustic vibrations), display (levitation), and audio. Most …

Applications in chemistry, biology, medicine, and engineering require the large-scale
manipulation of a wide range of chemicals, samples, and specimens. To achieve maximum …

Traditional food 3D printing technology, which primarily relies on mechanical control, often
faces challenges such as low resolution, stringent material requirements, limited flexibility …

A new level of freedom is made possible by orbital angular momentum (OAM), which can be
used to create twisted ultrasonic motors for particle manipulation and control. For steady and …

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 …
