Fig. 4. Directional jumping from a symmetry breaking 5-lobed LCE loop.

Fig. 4.

(A) Schematic illustrations of a 5-lobed LCE loop with an urethan acrylate glue bead crosslinked at the center of the one of the fibers in the loop and the big red arrow indicates the jumping direction. (B) Sequential images of the fibers during the one-step forward movement. (C) Overlaid sequential images showing the trajectory of the translational movement. (D) Moving distance of the loop as a function of time at 150° and 180°C, respectively. (E) Average displacement (red column) of a single jumping step moving forward and the average frequency (gray column) of the flipping motion at 150° and 180°C, respectively. (F) Sequential images of the 5-lobed LCE loop climbing up a 18° inclined hot plate. White dashed lines are used to guide the eyes. Scale bars, 2 cm.
