Bio-Inspired Soft Grippers Based on Impactive Gripping. [PDF]
Adv Sci (Weinh), 2021 According to movement ways and the classification model inspired by biological “grippers”, the soft grippers are divided into three types: non‐continuum bending‐type grippers, continuum bending‐type grippers, and continuum twisting‐type grippers. For each type of gripper, material properties, device architectures, and manipulation strategies are ...

Functional heterophasic liquid metals
Responsive Materials, Volume 1, Issue 1, August 2023., 2023 Adding metallic elements in the pure liquid metal (LM) (that forms heterophasic LMs) not only addresses the challenges but also brings appealing features into LMs. The heterophasic LMs broadly expand the applications of LM‐based systems in soft electronics, magnetic robot, catalysis, energy management, and biomedicine. Abstract Liquid metals (LMs) have

Development of a Stiffness‐Adjustable Articulated Paddle and its Application to a Swimming Robot
Advanced Intelligent Systems, Volume 5, Issue 5, May 2023., 2023 This work introduces a novel swimming paddle that can adjust the stiffness and its application to a non‐tethered swimming robot. The thrust modulation caused by stiffness change is comprehensively studied by varying frequency and range of motion. There is a threshold frequency dividing two regimes where one stiffness state excels over the opposite ...
