Researchers from University of Wisconsin-Madison have unveiled a new acoustic metamaterial capable of moving and rotating ...

A team of researchers has developed a way to use a light field to trigger a mechanical movement that will generate an acoustic wave. A team of international researchers led by engineers at ...

These waves rely on mechanical actions or movements, similar to how a toy car needs a force to move. Sound waves are a bit like those secret messages, but instead of spies, they're sent by objects ...

The station is uniquely durable and maintenance-free because of its simple mechanical construction ... electricity apace with the slow movements of the waves. An ordinary generator transforms ...
