About

Ryan Wing Hei Yu is pioneering the emerging field of soft robotics, with a particular focus on overcoming the fundamental limitations of deformable machines. His landmark 2022 paper, "Aquabots," introduced a revolutionary approach to fabricating ultrasoft robots using aqueous two-phase systems. By printing water-in-water constructs that self-assemble through phase separation, Yu created robots that are dramatically softer than traditional elastomer-based designs, enabling navigation through narrow, confined spaces previously inaccessible to soft robots. This work, which has already garnered 28 citations, addresses the critical "deformability constraint" that has long hampered the field. Yu's contributions are reshaping how researchers think about robot-environment interaction, particularly for biomedical applications where gentle tissue contact is essential. His innovative use of phase-separation-induced self-assembly represents a paradigm shift in soft robot fabrication, moving away from conventional molding and 3D printing toward more biologically inspired, bottom-up assembly methods. As the field of soft robotics continues to expand, Yu's water-in-water constructs are poised to enable a new generation of minimally invasive surgical tools and environmental sensors.
