Researchers at the Faculty of Physics at the University of Warsaw, with colleagues from Poland and China used liquid crystal elastomer technology to demonstrate a rotary micromotor powered with light. The 5-millimeter diameter ring, driven and controlled by a laser beam, can rotate and perform work, e.g. by rotating another element installed on the same axis.
