Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities

open access: yesAdvanced Intelligent Systems, EarlyView.
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

open access: yesAdvanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

4D Materials of Tough and Rapid Thermoresponsive Hydrogel by PET‐RAFT Polymerization

open access: yesJournal of Applied Polymer Science, EarlyView.
NIPAm‐containing bilayer hydrogels using a novel hydrogel formation method utilizing oxygen‐tolerant PET‐RAFT polymerization to investigate their temperature‐responsive behavior. The material properties strongly depend on NIPAm concentration and polymer density. Finally, we demonstrated a model gripper with optimized compositions.
