Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

open access: yesAdvanced 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 ...

Defect‐Engineered ZnO Nanowire Arrays for Flexible Room‐Temperature Hydrogen Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
Fabrication process of patterned ZnO nucleation sites on a flexible polyimide (PI) substrate. Top/tilted‐view SEM images of ordered ZnO nanoflower arrays confined within patterned circular regions. AFM topography map with height data revealing a disk‐array structure, where the patterned regions (marked by a red dot circle) are elevated by ∼2 µm ...

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Stirring‐Induced Modulation of NIR Emission in Tm3+‐Doped Nanoparticles: Evidence of Apparent Risetime Sensitivity

open access: yesAdvanced Optical Materials, EarlyView.
Motion was found to induce significant variation in the luminescence intensity ratio of NIR‐emitting Tm3+‐doped NaYbF4 nanoparticles, which has been ascribed to the population dynamics of the Tm3+ ion's excited states. These findings provide the groundwork for the design of motion nanosensors that can operate in environments not accessible with UV–vis ...
