Unipolar Muscle

Caption

In a study posted online Jan. 28 in the journal Science, University of Texas at Dallas researchers and their colleagues describe creating powerful, unipolar electrochemical yarn muscles that contract more when driven faster. This scanning electron microscope image shows a coiled unipolar muscle made from carbon nanotubes and coated with poly(sodium 4-styrenesulfonate). The outer coil diameter is approximately 140 microns, about twice that of a human hair.
