Scientists Devise A Way To Move Objects Without Touching Them, Using Ultrasound Waves
Telekinesis, or the ability to control things around us with our minds is a superpower we all wish we possessed, especially on those lazy days when getting up to even get the TV remote feels like a painstaking task. And now, researchers from the University of Minnesota have developed a new method for moving objects hands-free with the help of ultrasound waves, reveals an NDTV report. Previous attempts have been made that highlight that objects can be manipulated using light and sound waves. But that would only work when the objects were smaller than the wavelength of sound or light. In the new attempt, however, researchers have taken things to a whole new level by moving larger objects using the principle of metamaterial physics. To the unaware, Metamaterials are materials that are artificially engineered to interact with waves like light and sound. With a metamaterial pattern on the surface of an object, humans can use sound to move in a particular direction without touching the object at all.
