Summary: High-performance BCZT fiber crystals were grown using laser-heated pedestal growth, with varying stoichiometry achieved by changing growth rate. The optimized crystal showed larger energy storage density and higher EC responsivity compared to ceramic samples. These results suggest potential applications of BCZT as EC elements with controlled composition through fine-tuning growth parameters.

Summary: This study introduces low-radius Li+ into BaZr0.2Ti0.8O3 (BZT) through ion substitution engineering, leading to a change in internal lattice stress and a significant enhancement of the ferroelectric properties in BZT ceramics. Under the conditions of 333 K and 70 kV cm-1, the adiabatic temperature change of 5.7 mol% Li2CO3-doped BZT is 1.37 K, which is higher than that of pure BZT ceramics (0.61 K). Therefore, this work provides a simple but effective approach to design high-performance electrocaloric materials for next-generation refrigeration.

Summary: In this study, large and regulable electrocaloric effects at room temperature are achieved in PbZrO3/Ca3Mn2O7 bilayer films based on PbZrO3 phase transition, and the sign of adiabatic temperature change, ΔT, is determined by Ca3Mn2O7 thickness. The formed PbZrO3-Ca3Mn2O7 heterojunction reduces the carrier concentration of the film and establishes a built-in electric field, greatly enhancing the withstanding voltage of the bilayer films. A maximum positive ΔT of 66.5 K is obtained in the bilayer film with a thin Ca3Mn2O7 layer, while a negative ΔT of -9.9 K is obtained with a thick Ca3Mn2O7 layer, both near room temperature. This work presents a simple and effective approach to designing huge electrocaloric effects based on antiferroelectric-containing multilayers near room temperature.

Summary: This paper proposes a novel hybrid scheme for flag-type nanogenerators (FNGs) that enhances their performance and broadens their operational wind speed ranges by harnessing the synergistic potential of two aerodynamic behaviors. The proposed flag-type triboelectric-piezoelectric hybrid nanogenerator (FTPNG) integrates flapping piezoelectric flags (PEFs) and a fluttering triboelectric flag (TEF). The FTPNG achieves significant power generation and a broad wind speed range, surpassing other FNGs, making it suitable for various self-powered systems and Internet of Things applications.

Summary: Artificial Intelligence of Things (AIoT) aims to establish smart and informative interactions between humans and devices. However, common pixelated sensing arrays in AIoT applications present problems such as hard and brittle devices, complex structures, and low precision. This article introduces an innovative solution called the all-in-one intelligent semitransparent interactive nerve patch (AISI nerve patch), which integrates sensing, recognition, and transmission functionalities into a thin and flexible patch. The AISI nerve patch is semitransparent, allowing for accurate identification without affecting aesthetics, and it can be attached to any curved surface for intelligent and interactive applications. With rapid response time and high precision recognition, it enables the integration of artificial intelligence and achieves high recognition accuracy for further development of AIoT.
