Bilayered PEDOT:PSS–Collagen Scaffolds as Functional Architectures for Tissue Engineering

Advanced Materials Interfaces, EarlyView.
A bilayered scaffold integrates collagen and PEDOT:PSS as distinct yet interconnected 3D matrices, preserving their fibrillar and conductive characteristics. Spatial compartmentalization enables independent tailoring of each domain while maintaining mechanical stability and compatibility with electrochemical monitoring, providing a multifunctional ...

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Helicity‐Dependent All‐Optical Switching in Bi,Ga‐Substituted Rare‐Earth Iron Garnet Films Driven by Orbital Magnetic Moment

Advanced Optical Materials, EarlyView.
Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...
