Fiber-Based Artificial Muscles Get New and Powerful Twists (5 of 8)

Caption

Twist is inserted into a cylindrical carbon nanotube (CNT) sheet stack that surrounds a nylon yarn. The CNT cylinder automatically collapses to form a sheath around the nylon yarn, which transfers further twist insertion that causes coiling of the yarn. A scanning electron microscope image of an 87-micron outer-diameter coiled electrochemical SRAM is shown on the right. This material relates to a paper that appeared in the July 12, 2019 issue of Science, published by AAAS. The paper, by J. Mu at The University of Texas at Dallas in Richardson, TX, and colleagues was titled, 'Strain-programmable fiber-based artificial muscle.'
