Soft Electromagnetic Actuator and Oscillator

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work presents a groundbreaking soft electromagnetic system capable of bistable actuation and self‐regulated oscillation. Using liquid metal and silicone as a compliant conductor, the actuator enables force generation, sensing, and feedback with minimal power.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...

Quantitative Assessment of Gut and Vascular Barriers in TTOP, a Cartridge‐Based Bicompartmental Culture Platform

open access: yesAdvanced Materials Technologies, EarlyView.
The modular, versatile, and standardized cartridge‐based culture module allows to replicate gut and vascular barriers. Its conventional handling requirements facilitate adoption by non‐technical users, while the design allows safe manipulation and retrieval of samples for permeability assays and endpoint analysis.

Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.
