New metamaterial enables remote movement of objects underwater using sound

Breakthrough Metamaterial Leverages Sound Waves for Touch-Free Control of Submerged Objects

A new metamaterial enables sound waves to manipulate underwater objects with no physical contact, enabling easier and more accessible operation in aquatic environments. University of Wisconsin-Madison researcher Dajun Zhang presented the new metamaterial to peers on May 20 at the joint 188th Meeting of the Acoustical Society of America and the 25th International Congress on Acoustics. The work builds on other acoustic applications, like mapping …

Physics advance details new way to control solid objects in liquid

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The discovery will allow researchers to engineer technologies that make use of the technique to develop applications in fields such as biomedical testing and drug development.

New metamaterial enables remote movement of objects underwater using sound

Sound can do more than just provide a nice beat. Sound waves have been used for everything from mapping the seafloor to breaking apart kidney stones. Thanks to a unique material structure, researchers can now move and position objects underwater without ever touching them directly.

Scientists use sound waves to move objects underwater—without touching them

Sound doesn’t just help us hear music or communicate underwater—it can also be used to move objects without physically touching them. Thanks to new research from the University of Wisconsin-Madison, scientists have developed a special material that allows them to control the movement of floating or submerged objects using only sound waves. Dajun Zhang, a […] The post Scientists use sound waves to move objects underwater—without touching them app…
