Stable and efficient robotic artificial muscles built upon new material combinations

Actuators, which convert electrical energy into motion or force, play a pivotal role in daily life, albeit often going unnoticed. Soft material-based actuators, in particular, have gained scientific attention in recent years due to their lightweight, quiet operation, and biodegradability. A straightforward approach to creating soft actuators involves employing multi-material structures, such as "pockets" made of flexible plastic films filled with oils and coated with conductive plastics.
