Micro-actuators: when artificial muscles made of nematic liquid crystal elastomers meet soft lithography

J Am Chem Soc. 2006 Feb 1;128(4):1088-9. doi: 10.1021/ja0575070.


The production, via soft lithography, of micron-sized thermoresponsive pillars made of side-on nematic LCE leads to the formation of surface-responsive structures. The individual, monodisperse pillars, when cut out from the surface, behave as micro-actuators, showing contraction of around 35% at the nematic to isotropic phase transition.
