The Bubble-Powered Robot Revolution: How Sound Replaces Motors

from The Deep Dive Lab: Unraveling Materials Science · host Son Hoang

In this episode, we explore how researchers built artificial muscles powered entirely by ultrasound-driven microbubbles. These soft actuators bend, twist, and grip with incredible precision, enabling robotic skins, swallowable robots, and ultragentle biological manipulation.Source: Ultrasound-driven programmable artificial muscles.
