EMMETT WARREN, NEWS EDITOR [email protected]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 articleRelated content from Photonics MediaArticlesCustomized Optical Traps Improve 3D Trapping Efficiency in Large ParticlesIn optical tweezing, a process which involves using beams of light to trap microscopic objects, the smaller the volume of light that confines a microparticle, the more tightly the particle can be...BioPhotonics.com July 2024 IssuePhotoswitchable Materials Streamline Thermal RegulationThe design and development of functional materials with tunable thermal conductivity — for example, to ensure the thermal dissipation in microelectronics devices — is necessary to prevent...BioPhotonics.com May 2024 IssueNovel Photodiode Cuts Excess Noise, Enhances Detection EfficiencyResearchers at the University of Sheffield designed and developed an avalanche photodiode (APD) with significant potential for low photon detection.
