Sound waves power these tiny drones

EPFL engineers have developed miniature boats and drones that convert sound waves into controlled movement. Their resonators create directional thrust and could eventually enable even smaller robots that bend, vibrate, or change shape in response to sound.

瑞士洛桑联邦理工学院的工程师开发出能将声波转化为受控运动的微型船和无人机。这些共振器可以产生定向推力，未来或能用于制造更小、可随声波弯曲、振动或改变形状的机器人。
