ABSTRACT Twisted and coiled artificial muscles (TAMs) have been extensively studied in the field of soft robots due to their exceptional properties, including high energy density, large load‐to‐weight ratio, deformation, low driving voltage, hysteresis. The advancements TAMs hold potential for enhancing performance broadening functional capabilities robots, thus demonstrating substantial practical value. This review outlines recent progress diverse applications robots. First, commonly used materials fabricate TAMs, inorganic fibers, composite organic natural are discussed along with characteristics. Then, actuation strategies summarized across four aspects: thermal method, solvent electrochemical method other non‐contact methods. Moreover, configurations classified into single, parallel braided structures. In addition, various driven by introduced according functions, manipulation, locomotion, smart textile, sensor. Finally, research hotspots development trends evaluated. It is expected that this article can serve as a valuable reference source inspiration researchers actuators

Twisted nylon actuators (TNAs) are widely recognized in soft robotics for their excellent load-to-weight ratio and cost-effectiveness. However, limitations deformation output force restrict ability to support more advanced applications. Here, we report 3 performance-enhancing strategies inspired by the construction process of chromosome, which validated through novel types TNAs. First, design a dual-level helical structure, demonstrating remarkable improvements (60.2% vertically approximately 100% horizontally) energy storage capability (launching miniature basketball 131 cm height). Second, present parallel-twisted method, where TNAs reaches 11.0 N, achieving 12.1% contraction under load 15 N (10,000 times its weight). Additionally, construct structure based on TNAs, resulting 439.7% improvement capability. We have adopted several applications: (a) two bionic elbows capable rotating shooting over 130 cm; (b) robot that can rapidly jump 30 (c) finger achieves contracting (15.3% 2 kg load), precise bending (tracking errors less than 2.0%), twisting motions. This work presents approaches fabricating high-performance explores potential applications these driving robots with multifunctional capabilities.

ABSTRACT The escalating prevalence of skeletal muscle disorders highlights the critical need for innovative treatments severe injuries such as volumetric loss. Traditional treatments, autologous transplants, are constrained by limited availability and current scaffolds often fail to meet complex clinical needs. This study introduces a new approach loss treatment using shape-memory polymer (SMP) based on block copolymers perfluoropolyether polycaprolactone diol. SMP mimics biomechanical properties natural muscle, exhibiting low elastic modulus (2–6 MPa), high tensile strength (72.67 ± 3.19 exceptional toughness (742.02 23.98 MJ m−3) superior biocompatibility, thereby enhancing tissue integration regeneration within 4 weeks. Moreover, polymer's behavior ability lift >5000 times its weight showcase significant potential in both disorder prosthetic applications, surpassing existing scaffold technologies. advancement marks pivotal step development artificial muscles use.
