A soft exosuit is a lightweight wearable assistive device built with flexible textile materials, differing greatly from traditional rigid frame exoskeleton equipment. Instead of heavy metal and alloy structures, it uses elastic fabrics, tension cables and compact drive components to closely attach to the human body like functional clothing. By delivering targeted tensile assistance to key muscle groups and joints, it effectively shares the physical load during bending, lifting and long-hour standing work. The soft design ensures excellent wearing comfort and unrestricted limb mobility, allowing users to perform delicate operations freely. It can also collect real-time motion data to adjust auxiliary output adaptively according to movement frequency and posture changes. Widely used in industrial labor protection, sports training and early-stage rehabilitation, the soft exosuit relieves cumulative muscle fatigue, reduces the risk of chronic strain injuries, and features convenient wearing, portability and easy maintenance. With its lightweight and highly adaptable features, it breaks the bulky limitations of traditional exoskeletons and expands the application scope of wearable auxiliary technology.
