About

Loon‐Seng Tan is a leading researcher in stimuli-responsive polymers and soft robotics, with a focus on azobenzene-functionalized materials that convert light into mechanical motion. His work addresses fundamental challenges in photomechanical actuation, including the design of bistable arches that enable rapid, remotely triggered deformation with precise control over light intensity and polarization. Tan has also investigated the relaxation dynamics and strain persistency of azobenzene-based polymers, providing critical insights into how these materials retain or dissipate photoinduced deformation over time—a key factor for practical actuator performance. His collaborative research on Nylon 6 films, featured in *Advanced Materials*, demonstrated four distinct modes of autonomous locomotion, showcasing how common polymers can harvest energy and information from their environment. While his most-cited papers have accumulated modest citation counts (10, 6, and 4 citations respectively), they represent foundational contributions to the emerging field of soft robotics and adaptive materials. Tan’s work is particularly notable for bridging fundamental polymer physics with application-driven design, offering pathways toward self-regulating, environmentally responsive systems.
