研究人员想用碳纤维造出一种有些柔韧性和高强度的材料，比如像人的肌肉那样的性质，所以想到了使用有机硅橡胶（PDMS）材料和碳纤维相结合的形式，采用了螺旋结构，造出的材料可以够承受 12600 倍于自身的质量.
文献：Theory of the tensile actuation of fiber reinforced coiled muscles，
There is a strong need for compact artificial muscles capable of applying large contractile strokes and lift heavy weights. Coiled fibers recently emerged as attractive candidates for these purposes, owing to their simple construction and the possibility of their thermal, electrical and chemical actuation. An intuitive theoretical understanding of the mechanics of actuation of these muscles is essential for the enhancement of their performance and can pave the way for the development of new applications and technologies. In this paper, a complete theoretical model for the tensile actuation of fiber reinforced artificial muscles is presented and experimentally validated. The model demonstrates that all muscles made from the same material have a universal behavior, which can be described by a single master curve. It enables the systematic design and understanding of coiled muscles for specific performance owing to a comprehensive mathematical correlation among the geometry, materials properties, and actuation. Carbon fibers (CF)/ polydimethylsiloxane (PDMS) coiled muscles are demonstrated as simple to fabricate yet powerful muscles owing to the availability of high strength CF. In addition to showing excellent agreement with the theoretical models, they can be actuated by joule heating or chemical swelling, lift up to 12,600 times their own weight, support up to 60 MPa of mechanical stress, provide tensile strokes higher than 25%, and a specific work up to 622 J/kg, the latter is more than 15 times higher than that of natural muscles.
