Advances in Electroactive Liquid Crystal Elastomers for Intelligent Robotics and Electronics

Advanced Robotics Research, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) integrate molecular anisotropy with electrical functionality to enable programmable actuation and reconfigurable electronics. This review classifies eLCEs into robotic actuators and adaptive electronics, summarizes key actuation mechanisms, and highlights fabrication strategies that bridge materials to ...

Investigation of Optical Characteristics of Silica- and Polymer-based Photonic Crystal Fibers

, 2007
我們研究在製作塑膠光子晶體光纖時相關的重要參數，並利用相同的製程製造出各種不同結構的塑膠光子晶體光纖，只要在光纖的微結構上做些釭瘍雂ぇK可以得到截然不同的光纖特性。接著，我們對各種不同結構的塑膠光子晶體光纖研究其光學特性，包含具有實心核心及環形結構的光纖。我們證明所製作出具有實心結構的光纖可以在非常寬的頻段內保持單模狀態，其頻段至少由600至1600奈米。我們亦證明具有較大空孔率的實心結構光纖能具有多模模態，而該光纖能傳輸的模態可以利用有限差分法精確地加以預測。經由實驗跟模擬 ...

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

In Situ X‐Ray Tomography and Acoustic Emission Monitoring of Damage Evolution in C/C‐SiC Composites Fabricated by Liquid Silicon Infiltration

Advanced Science, EarlyView.
This study investigates how the internal structure of fiber‐reinforced ceramic composites affects their resistance to damage. By combining 3D X‐ray imaging with acoustic emission monitoring during mechanical testing, it reveals how silicon distribution influences crack formation.

Design and analysis of thermally tunable liquid-crystal-filled microstructured polymer optical fiber

, 2012
A highly tunable bandgap-guiding microstructured polymer optical fiber (mPOF) is designed by infiltrating the cladding air holes with a liquid crystal. Bandgap is blue shifted as temperature is increased.

Pholidota‐Inspired Electronic Skin Possessing Terahertz‐Wave Reflection–Absorption–Transmission Switchability

Advanced Science, EarlyView.
The pholidota‐inspired electronic skin is successfully constructed, originally realized four‐state reversible switching of terahertz‐wave reflection, absorption, transmission, and secondary reflection. In response to external demands, it issues deformation instructions, verifies the deformation state after the equipment executes the action, and thus ...
