Cell Contractile Force‐Mediated Morphogenetic Tissue Engineering via 4D Printed Degradable Hydrogel Scaffolds

open access: yesAdvanced Science, EarlyView.
Through the actuation of cell contractile forces, geometrically complex structures are formed via a bioprinted, rapidly degrading cell‐laden hydrogel system, resulting in cell‐only condensation within a few days of culture. This system supports stem cell differentiation down different lineages and new tissue formation, such as chondrogenesis and ...

From Knitting Technology to Robotics: Untethered Thermally Actuated Textile Exoskeleton for Dexterity Applications

open access: yesAdvanced Science, EarlyView.
A textile‐based exoskeleton glove with integrated thermally driven actuators achieves rapid, low‐power response for dexterous motion. Utilizing advanced knitting methods, embedded heaters, and hybrid yarn sensors, the glove bends in a segmented fashion under 12 s at only 10.8 W and 48 °C.
