Soft actuators and robotic devices designed for rehabilitation assistance are a rapidly growing field of research. Their inherent flexibility enhances comfort usability without restricting the user's natural range motion. However, despite these advantages, there still several challenges that need to be addressed before systems can commercialized. This paper presents comprehensive review latest developments in soft wearable robots, also known as exosuits. exosuits composed two main components: actuation mechanisms (how forces/torques generated) physical interfaces where robot is anchored body). reviews advances areas, while categorizing based on intended assisted joint, degrees freedom (DOF), device type. The systematic literature follows PRISMA guidelines summarize relevant studies investigate their related interface, mechanism its design. Several limitations were identified insights into potential future research directions presented. In future, goal should develop an untethered assistive provide multiple joints having low form factor, intuitive being comfortable user.

Abstract Energy‐efficient yet energy‐dense soft actuators are essential for untethered wearable robots. This work reports a fabric‐like actuator, combining shape memory alloy (SMA) springs and electrostatic clutches (ESClutches). The SMA provide high force density, with only 18 g of materials generating 40 N at actuation strains over 35%, but requiring 78 W power to hold that strain. ESClutches cannot generate motion on their own, can maintain the contraction generated by SMAs consuming few mW, thus allowing be turned off. By ESClutches, fabric actuator is developed stroke suited an upper‐limb exoskeleton, able lock in any given position using negligible power. design scalable: number dimensions chosen meet size performance requirements. two use cases, where combined consume 70% lower than alone.
