Acoustic manipulation in microfluidic systems exploits the interaction between sound waves and fluids to exert precise, contactless control over particles, droplets and cells. By generating acoustic ...

Parametric acoustic waves exploit the nonlinear interaction of high-frequency ultrasonic beams in a medium to produce low-frequency sound with exceptionally narrow beamwidths. By transmitting two ...

Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound ...

Wow. [Yoichi Ochiai], [Takayuki Hoshi] and [Jun Rekimoto] are researchers from the University of Tokyo and the Nagoya Institute of Technology, and they have just learned how to airbend. Using a series ...

Acoustic tweezers are based on focused acoustic vortices and hold promise to precisely manipulate microorganisms and cells from the millimeter scale down to the submicron scale, without contact, and ...

This research is due to be presented in August in Vancouver (Canada) at SIGGRAPH, the most important conference on computer graphics and interactive techniques where companies such as Nvidia, Disney ...

The metamaterial created by Zhang is used to push and rotate an object adorned with the University of Wisconsin’s Bucky the Badger. NEW ORLEANS, May 20, 2025 – Sound can do more than just provide a ...

Engineers in Switzerland have successfully levitated both a particle of instant coffee and a droplet of water using high frequency sounds to make them collide. The result was a very tiny cup of coffee ...

Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and magnetic fields -- and to sound.

Mechanical engineers are using two electronic 'voices' singing a harmonic duet to control suspended particles and cells in new and valuable ways. Their prototype device can form and rotate a ...
