Sound Waves Can Be Used To Move Objects Like A Tractor Beam, Even Around Obstacles
Over the retiring several decades , scientists have developed optical and acoustic tweezers . Using illumination or legal waves , they can hook and control the motion of a small object , like a tinytractor beam . These are exciting maturation , but have very stringent requirements to work . Researchers have now developed a new way to move and manipulate object at a length , still using sound , that allow them to move on complex paths ....
