Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Solvent‐Rich Pre‐Coagulation Bath for Tunable Liquid‐State Fusion Enables Robust Two‐Step Polymer Embedded Printing

Advanced Science, EarlyView.
Additive manufacturing enables complex structures, but polymer printing often suffers from poor interlayer fusion and defects induced by heat or binders. A two‐step, room‐temperature strategy based on immersion phase separation (IPS‐E3DP) achieves precise liquid‐state fusion with high structural fidelity, enhanced mechanical performance, broad material

4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

Advanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.
