Thermomechanical liquid crystalline elastomer capillaries with biomimetic peristaltic crawling function.It is highly desirable to fabricate liquid crystalline elastomer (LCE) devices with novel functions for applications in different areas.  Reversible thermomechanical contraction and expansion are observed for the LCE capillaries, which show a relative contraction of 16% in the length and a relative expansion of 12% in the diameter upon the nematic to isotropic phase transition.
