Double Helix Structure for Stable Flexural Actuation in Soft Robotics
Advanced Intelligent Systems, EarlyView.This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Pre‐Curved Everting Robots With Embedded Steering Intelligence Fabricated by CO2 Laser Welding
Advanced Intelligent Systems, EarlyView.Design and experimental demonstration of a laser welded growing robot for anatomically guided navigation. The robot follows an aortic arch phantom entering the branchiocephalic branch through steering by design. The figure shows the physical phantom setup, CAD defined weld geometry and full robot eversion.

Advanced Intelligent Systems, EarlyView.Fabrication shapes soft robot performance, but benchmarking data and selection guidelines remain scarce. We fabricate silicone actuators using two molding techniques and three mold types, characterizing them with cycle testing, microscopy, profilometry, and 3D imaging. Applying our lab‐scale, soft robotics‐specific fabrication evaluation criteria shows

Hydraulic function of medullary bundles in a tropical root climber
American Journal of Botany, EarlyView.Abstract Premise Medullary bundles, which are vascular bundles in the pith, have evolved multiple times. However, their functional significance remains poorly understood. Here, we investigated how medullary bundles are involved in the vascular architecture and hydraulic function in a tropical root climber, Adelobotrys scandens (Melastomataceae) to ...

Blade vibration parameter identification method based on blade tip-timing signals
Journal of Physics: Conference SeriesAbstract Blade Tip Timing (BTT) is a widely used non-contact technology for vibration monitoring in rotating machinery. Due to its inherent issue of undersampling, traditional frequency identification methods often struggle to accurately identify asynchronous vibration frequencies of the blades. To address this issue, this paper proposes

Cellular basis for blade splitting in bull kelp, Nereocystis luetkeana
American Journal of Botany, EarlyView.Abstract Premise Blade splitting in bull kelp, Nereocystis luetkeana is central to thallus development and function, yet the cellular basis of this process remains poorly understood. Two historical models proposed contrasting mechanisms: One attributes blade separation primarily to programmed cell death, whereas the other suggests mechanical tearing ...
