Presented technology ultrasound levitation, envelope obstacles

Physicists from the University of Sussex became the first to introduce ultrasonic levitation technology, which is capable of bending the waves to bypass obstacles.

The researchers team developed a SoundBender device, which is an interface that creates a dynamic self-discharge radiation that holds a small object in the air and allows you to tactfully feel the repellent effect. However, the uniqueness lies in the complexity of the sound field, and the ability to overeat on his way of obstacles.

Physics were able to achieve this using a hybrid system, which combines the versatility of phased solutions of converters and accuracy of acoustic metamaterials. In addition to levitation, with ultrasound, you can manipulate non-rigid objects, for example, a flame of a candle or water. The principle of technology of technology is similar to holographic visualization.

The advantage of sound levitation is that it does not require any specific physical properties, such as magnetic or electrical, in a manipulated object. Now scientists work on the extension of the frequency range of the device. This would allow, for example, to create zones of silence in noisy premises. In the future, the technology can be used to improve interactivity in museums and games, fire control, evaporation, liquids and synchronization with music.

No less amazing technology is developing a startup MAP. He plans to launch a blockchain platform that
