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 ...

Spectral Condensing of All‐Dielectric Structural Colors via Cascaded Formation of Self‐Similar Beams

Advanced Optical Materials, EarlyView.
Standalone low‐index microscale ridges (MRs) are promising platforms for all‐dielectric structural color generation. They are compact and easy to fabricate, but their color purity trails behind that of resonator‐ or periodic pattern‐based structural color pixels.

Energy‐Transfer‐Driven Programmable Luminescence in Bi3+‐Eu3+ Co‐Doped Na3Ca2TaO6 Phosphors Toward Multifunctional Optical Applications

Advanced Optical Materials, EarlyView.
Energy transfer from broadband Bi3+ sensitizers to Eu3+ emitters enables composition‐, excitation‐, and temperature‐dependent luminescence in Na3Ca2TaO6. These controllable optical states support ratiometric thermometry and excitation‐selective, filter‐assisted information decoding in flexible phosphor–polydimethylsiloxane films, demonstrating how ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

Advanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Scalable Task Planning via Large Language Models and Structured World Representations

Advanced Robotics Research, EarlyView.
This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.
