Ambient‐Stable Transparent P‐Type CuI Transistors Via Room‐Temperature Pulsed Laser Deposition

Advanced Functional Materials, EarlyView.
An in situ PLD fabricated AlOx${\rm AlO}_x$/CuI/AlOx${\rm AlO}_x$ sandwich structure enables stable CuI TFTs with a field‐effect mobility of 2.3 ±$\pm$ 0.7 cm2${\rm cm}^{2}$ V−1${\rm V}^{-1}$ s−1${\rm s}^{-1}$ and excellent ambient stability. Complementary inverters based on CuI:Rb and ZnO:Al exhibit rail‐to‐rail voltage transfer characteristics and an

Tissue‐Adhesive Fabric‐Based Bioelectronics for Wearable and Implantable Applications

Advanced Functional Materials, EarlyView.
An implantable and wearable bioelectronic textile (iTextile) is introduced as a unified platform bridging wearable and implantable systems. By integrating a self‐healing polymer, stretchable silk fabric, conductive composite electrodes, and an adhesive hydrogel, the platform enables conformal, stable interfacing with soft tissues. The iTextile supports

Polarization‐Dependent Synaptic‐Like Electro‐Optical Response in Ferroelectric Nematic Liquid Crystals

Advanced Functional Materials, EarlyView.
Ferroelectric nematic liquid crystals (FNLCs) offer fast, tunable polarization and low‐voltage operation but suffer from poor polarization retention at zero field. Semiconductor‐modified FNLCs enhance polarization retention and exhibit short‐ and long‐term electro‐optical responses, while also supporting spike‐type signal integrations.

Mechanically Mutable Matrices: A Hierarchical Investigation of Decellularized Sea Cucumber Collagen as an Adaptable Scaffold Material

Advanced Functional Materials, EarlyView.
Sea cucumber mutable collagenous tissue (MCT) is a remarkable collagen‐based material which can rapidly undergo large changes in stiffness through transiently bound effector proteins. Here, we investigate the hierarchical structure and mechanical response of MCT from Cucumaria frondosa across length scales with a wide range of methods, also exploring ...
