Anisotropic Heat Transfer in a Fibrous Membrane with Hierarchically Assembled 2D Materials.

Effective heat redistribution in specific directions is vital for advanced thermal management, significantly enhancing device performance by optimizing spatial heat configurations. We have designed and fabricated a hierarchical fibrous membrane that enables precise heat directing. By integrating hierarchical structure design with the anisotropic thermal conductivity of two-dimensional (2D) materials, we developed a fibrous membrane for anisotropic heat transfer.

Facile, scalable, and adaptive infrared reflection towards soft systems by blowing a Janus rubber film.

Controllable IR-reflection systems can be applied to displays, adaptive military camouflages, thermal managements, and many other fields. However, current reported controllable IR-reflection systems suffer from utilizing rigid materials, complicated devices, or high working temperature/voltage, which are not suitable for their widespread applications toward soft systems. Herein, inspired by cephalopods, we demonstrate a facile and scalable method for adaptive IR reflection based on a Janus rubber film, which is composed of aluminum-coated microsheets (AMSs)/rubber composite top and a rubber only bottom.

Compressible and Stretchable Magnetoelectric Sensors Based on Liquid Metals for Highly Sensitive, Self-Powered Respiratory Monitoring.

Healthcare monitoring, especially for respiration, has attracted tremendous attention from academics considering the great significance of health information feedback. The respiratory rate, as a critical health indicator, has been used to screen and evaluate potential illness risks in early medical diagnoses. A self-powered sensing system for medical monitoring is critical and imperative due to needless battery replacement and simple assembly.
