Sound waves power these tiny drones

Engineers have found a fascinating way to power tiny drones using sound waves, something we encounter every day! This innovative technology relies on Helmholtz resonance, which allows sound waves to create thrust and movement. By 3D printing various cavities, the team was able to design miniature boats and drones that respond to specific frequencies. Imagine the possibilities as these devices could get even smaller and more advanced, potentially changing shape in response to sound!
