Artificial Muscles from Fishing Line and Sewing Thread
Carter S. Haines,Márcio D. 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 E. Kozlov,Seon Jeong Kim,Xiuru Xu,Xiuru Xu,Benjamin J. Swedlove,Gordon G. Wallace,Ray H. Baughman +21 more
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
Ultrafast charge and discharge biscrolled yarn supercapacitors for textiles and microdevices
Jae Ah Lee,Min-Kyoon Shin,Shi Hyeong Kim,Hyun U. Cho,Geoffrey M. Spinks,Gordon G. Wallace,Márcio D. Lima,Xavier Lepró,Mikhail E. Kozlov,Ray H. Baughman,Seon Jeong Kim +10 more
TL;DR: Weavable, sewable, knottable and braidable yarns that function as high performance electrodes of redox supercapacitors that deliver high energy and power densities for the applications in electronic textiles are demonstrated.
Journal ArticleDOI
Synergistic toughening of composite fibres by self-alignment of reduced graphene oxide and carbon nanotubes.
Min Kyoon Shin,Bommy Lee,Shi Hyeong Kim,Jae Ah Lee,Geoffrey M. Spinks,Sanjeev Gambhir,Gordon G. Wallace,Mikhail E. Kozlov,Ray H. Baughman,Seon Jeong Kim +9 more
TL;DR: Toughness is sensitive to the volume ratio of the reduced graphene oxide flakes to the carbon nanotubes in the spinning solution and the degree of graphene oxidation, which acts to deflect cracks and allow energy-consuming polymer deformation.
Journal ArticleDOI

Shi Hyeong Kim,Shi Hyeong Kim,Carter S. Haines,Na Li,Keon Jung Kim,Tae Jin Mun,Changsoon Choi,Jiangtao Di,Young Jun Oh,Juan Pablo Oviedo,Julia Bykova,Shaoli Fang,Nan Jiang,Zunfeng Liu,Run Wang,Prashant Kumar,Rui Qiao,Shashank Priya,Kyeongjae Cho,Moon J. Kim,Matthew Lucas,Lawrence F. Drummy,Benji Maruyama,Dong Youn Lee,Xavier Lepró,Enlai Gao,Dawood Albarq,Raquel Ovalle-Robles,Seon Jeong Kim,Ray H. Baughman +29 more
TL;DR: These carbon nanotube yarn harvesters were used in the ocean to harvest wave energy, combined with thermally driven artificial muscles to convert temperature fluctuations to electrical energy, and used to power a light-emitting diode and to charge a storage capacitor.
Journal ArticleDOI
