Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications

Advanced Science, EarlyView.
A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

Advanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

Stroke Volume Determination by Echocardiography

Chest, 2022
Basic critical care echocardiography emphasizes two-dimensional (2D) findings, such as ventricular function, inferior vena cava size, and pericardial assessment, while generally excluding quantitative findings and Doppler-based techniques. Although this approach offers advantages, including efficiency and expedited training, it complicates attempts to ...
