Keita Receives Best Presentation Award

We are pleased to share that Mr. Keita Okano, a master’s student at the University of Tsukuba, has been recognized at the Multiphase Flow Symposium 2025, held at Kobe University from September 3–5, 2026. His presentation received both the: Presentation Title “Rotational and mixing dynamics of an acoustically levitated droplet using phased array” Authors: Mr.Continue reading “Keita Receives Best Presentation Award”

2025 Ultrasonic AsPIRE Conference

On May 2nd, 2025, we held the Ultrasonic AsPIRE Conference at the University of Tsukuba—a small, focused workshop with 14 participants dedicated to the exploration of ultrasonic manipulation and wave-based interfaces. Although modest in scale, the event was intentionally scheduled to align with other international conferences, including CHI 2025 in Yokohama, which made it convenientContinue reading “2025 Ultrasonic AsPIRE Conference”

Our Lab at JST Science Agora 2024

On Saturday, October 26th and Sunday, October 27th, 2024, our laboratory participated in JST Science Agora, Japan’s largest public science communication event. We presented live demonstrations of our research, including: We had many enthusiastic visitors and enjoyed exciting interactions with people of all ages. It was a fantastic opportunity to share our work and sparkContinue reading “Our Lab at JST Science Agora 2024”

Holographic Microfluidics

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”

HIFU Embossment

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”

Acoustophoretic Volumetric Display (AVD)

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)”
