Phase Engineering for Enhanced Piezoresponse in P(VDF‐TrFE) and Its Composites
Advanced Materials Interfaces, EarlyView.As the temperature approaches the Curie point, the crystalline phase in P(VDF‐TrFE) decreases proportionally, while the amorphous phase increases. This shift leads to the formation of more interphase regions. Although spontaneous polarization from crystalline regions decreases, the interphase regions enable additional deformation, thereby enhancing the

Advanced Materials Technologies, EarlyView.This study presents a braided fiber‐reinforced sleeve that amplifies strain in soft materials, enhancing their performance in stretchable devices like sensors and energy harvesters. By reinforcing and elongating encased materials, the sleeve increases the “effective” strain.

How to Manufacture Photonic Metamaterials
Advanced Materials Technologies, EarlyView.Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Energy Focusing Metasurface Based Wireless Power Transfer System for Compact Unmanned Mobilities
Advanced Optical Materials, EarlyView.A miniaturized wireless power transfer system integrates a metasurface lens, microstrip patch antenna, and RF‐CMOS rectifier to enhance mmWave reception efficiency and reduce size. Leveraging mmWave short wavelengths, it achieves high gain on small platforms. The system's polarization independence and wide‐angle reception ensure robust performance.
