Airborne ultrasound phased arrays are increasingly used for mid-air haptics, acoustic levitation, and emerging “odor/volatile steering” concepts. A common, often under-quantified companion to these applications is mid-air acoustic streaming—steady air motion driven by ultrasound. Streaming can alter perceived haptic cues, destabilize levitated objects, and transport aerosols or vapors, so understanding it is a prerequisite forContinue reading “Modelling of Acoustic Streaming in Phased Array Transducer”

We propose a microfluidic system using focused ultrasound through a hydrophobic mesh to manipulate droplets on its surface, offering an alternative to Electrowetting-on-Dielectric (EWOD) systems. This method enhances droplet jump height and flexibility. A phased array transducer dynamically creates foci, controlling droplets up to 300 µL with jump heights up to 10 cm, a 27-foldContinue reading “Holographic Microfluidics”

We propose High-Intensity Focused Ultrasound (HIFU) as an innovative method for creating custom embossed designs on acrylic surfaces, eliminating the need for traditional molds. By adjusting HIFU parameters such as amplitude, irradiation time, and distance, we can control embossment qualities like height, transparency, and line precision. This technique offers significant advantages for quick prototyping andContinue reading “HIFU Embossment”

AVD is one of the latest application of acoustic levitation. Any display, including the ones on your computer, tablet or smartphone uses after image effect on your eyes to visualise information on your screen. AVD uses the same principle, and levitated particle (about 1 mm) move rapidly in space under the illumination of RGB LED.Continue reading “Acoustophoretic Volumetric Display (AVD)”
