Monolithic UV‐Laser Programming of Photothermally Meta‐Morphing SMA Structures: Dual‐Encoded Kirigami Mechanics and Photonic Absorbance

open access: yesAdvanced Science, EarlyView.
A monolithic manufacturing strategy is presented for photothermal shape memory alloy (SMA) meta‐morphing structures. Using a single‐step UV‐laser process, the mechanical compliance is programmed via kirigami patterning while optical absorbance is simultaneously tuned through surface oxidation.

Non‐Invasively Tracking an Arbitrary Deformable Object Through Scattering Media and Around Corners via Speckle Correlations

open access: yesAdvanced Science, EarlyView.
A speckle correlation centroid localization method (SCCLM) is proposed for non‐invasive tracking of an arbitrary deformable object through scattering media and around corners, requiring no prior information. Its effectiveness is demonstrated not only in tracking hidden objects beyond the memory effect region but also in following objects undergoing ...

Bioinspired Morphology‐Decoupled Soft Gripper with Enhanced Bidirectional Grasping Capability

open access: yesAdvanced Science, EarlyView.
Inspired by biological predation, a novel gripper decouples cross‐modal grasping via dual morphological configurations. Synergistically integrating hybrid rigid and soft coupled fingers with a metamaterial palm, the system performs active compliant grasping for static objects and passive cage capture for dynamic targets.

Covalent Bonds Reinforced Strength and Modulus of Heterocyclic Aramid Fiber by Interfacial Aminated‐MXene Nanosheets

open access: yesAdvanced Science, EarlyView.
We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...
