Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk
Advanced Intelligent Systems, EarlyView.A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...

Advanced Intelligent Systems, EarlyView.An intelligent piezoelectric vibration control system integrating self‐sensing, autonomous operation, and adaptive bias‐flip synchronized switching damping (SSD) is developed. The system detects vibration extrema, executes synchronized switching control, and autonomously establishes the bias voltage without external sensing instruments, achieving ...

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots
Advanced Intelligent Systems, EarlyView.A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

Journal of Applied Polymer Science, EarlyView.Charpy impact performance of material‐extruded PLA is governed by the coupled effects of layer height, raster angle, and infill geometry. Full‐factorial testing identifies layer height as the dominant factor and reveals a strong layer‐height–raster‐angle interaction.
