Strain‐Activated Mechanical Metamaterial With Programmable Dual‐Phase Stiffness and Enhanced Energy Absorption

Advanced Materials Technologies, EarlyView.
A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.

Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

Advanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

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
