Microrobots powered by sound can move, steer and even fly, revealing a new propulsion system for tiny robotic machines.

Engineers from Switzerland have innovated remarkable microfliers and miniature boats that harness sound waves for propulsion.

The technology was developed by EPFL's MicroBioRobotic Systems Lab in Switzerland, and the study was published in Science ...

Over the past several decades, researchers have been getting better and better at manipulating tiny particles with acoustic waves. Dubbed "acoustic tweezers," the technology started with the ...

In either the 1850s or 1860s, German physicist Hermann von Helmholz created a device to analyze sound. In 2005, that same sort of device made its way into the airbox of the new 3.8-liter flat-six of ...

A new study on locally resonant metaplates points to an interesting application for 3D printing: structures that mechanically ...
