What are some examples of soft robotic actuators used in wearable exoskeletons for assisting individuals with mobility impairments or enhancing human performance in industrial settings, and how do they provide powered assistance, ergonomic support, or fatigue reduction for improving mobility, safety, and productivity?

Examples include pneumatic artificial muscles, shape-memory alloy actuators, and compliant mechanisms integrated into wearable exoskeletons. These actuators apply assistive forces, reduce muscle fatigue, and support ergonomic movements, enhancing mobility, reducing injury risk, and improving work efficiency for users with mobility impairments or workers in physically demanding tasks.
