TL;DR: In this article, high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles.
Journal ArticleDOI
Polymer artificial muscles
TL;DR: The various types of natural muscle are incredible material systems that enable the production of large deformations by repetitive molecular motions as mentioned in this paper. But they are difficult to manipulate and require a large amount of energy.
Haines et al Science 2014 SM - Artificial Muscles from Fishing Line and Sewing Thread
Carter S. Haines,Marcio Dias Lima,Na Li,Geoffrey M. Spinks,Javad Foroughi,John D. W. Madden,Shi Hyeong Kim,Shaoli Fang,Mônica Jung de Andrade,Fatma Göktepe,Özer Göktepe,Seyed M. Mirvakili,Sina Naficy,Xavier Lepró,Jiyoung Oh,Mikhail Kozlov,Seon Jeong Kim,Xiuru Xu,Benjamin J. Swedlove,Gordon G. Wallace,Ray H. Baughman +20 more
TL;DR: It was demonstrated that inexpensive high-strength polymer fibers used for fishing line and sewing thread can be easily transformed by twist insertion to provide fast, scalable, nonhysteretic, long-life tensile and torsional muscles.
Patent
Conducting polymer actuator
TL;DR: In this paper, stretch aligned conducting polymers are used as active members of actuators to achieve force per unit area of at least 10 MPa, when an electrical potential is applied across the electrolyte between the active member and the counter electrode.
