image: Lateral and cross-sectional views of a twisted carbon nanotube yarn (CNT) (left) and an SRAM made by coating a twisted CNT yarn with a polymer sheath. A scanning electron microscope image of a 42-micron outer-diameter coiled 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.' view more
