Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

Advanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

UCST‐Driven Shape Morphing in Digital Light Processing 4D‐Printed Hydrogels

Advanced Materials Technologies, EarlyView.
A DLP‐printable UCST hydrogel based on poly(acrylic acid‐co‐acrylamide) enables reversible thermally induced expansion and 4D shape morphing. Rational control of composition, porosity, and multimaterial architecture enables predictable 4D shape morphing through differential swelling and localized actuation, opening new opportunities for high‐resolution

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

Advanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

Advanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...
