The dynamic behaviors of the liquid marbles were monitored by a high-speed camera. Driven by the sound field, the liquid marbles moved toward each other, collided, and eventually coalesced into a ...

Novosund has created an ultrasound sensor that allows real-time blood pressure sensing without any cuff hassles. It is ready for smartwatches, and even rings.

Levitation is something ripped straight out of science fiction, however one London-based start up has developed a device which can raise and manipulate small objects with sound ... Pressure Cage ...

Method 2: Acoustic Levitation. Acoustic levitation involves using sound waves to generate enough pressure on an object that it counteracts the force of gravity. When sound waves interact with a solid ...

Imagine a high-speed train that travels through a tube at close to the speed of sound: What sounds like science fiction may soon become reality. It consists of a system of low-pressure tubes, through ...

In addition, as the sound pressure increases, the sound flow also affects the stability of the acoustic levitation. Comsol was used to nu-merical simulation the spatial sound field, pressure field and ...

Sound waves, particularly ultrasonic waves, can radiate high pressure and create areas of high pressure, known as acoustic traps. Particles and objects can become trapped in these areas, where ...
