Researchers at the University of Warsaw’s Faculty of Physics collaborated with researchers from the Polish Academy of Science and Xi’an Jiaotong-Liverpool University to demonstrate a rotary micromotor powered with light using liquid crystal elastomer technology. The 5-mm-diameter ring, driven and controlled by a laser beam, can rotate and perform tasks by rotating another element installed on the same axis. Liquid crystal elastomers (LCE) are a group of materials that enable construction of small, moving, or mobile devices. Research on these materials focuses on design of...Read full article

    piezoelectric
    Piezoelectricity is a property exhibited by certain materials in which they generate an electric charge in response to mechanical stress or deformation, and conversely, undergo mechanical deformation when subjected to an electric field. This phenomenon was discovered by Pierre and Jacques Curie in the late 19th century. The word piezoelectric originates from the Greek word "piezo," meaning to squeeze or press. The effect occurs due to the unique crystal structure of piezoelectric...
