Microfluidic Valve‐Integrated Garment for Smooth Sequential Gradient Mechanotherapy
Advanced Intelligent Systems, EarlyView.We present a soft wearable sleeve that delivers smooth, gap‐free compression using overlapping air‐filled actuators and tiny microfluidic valves. The system reduces bulk, lowers power needs, and uses a smartphone‐sized control box. It can provide sequential gradient compression, gradient pressure holding, and fast deflation, supporting more portable ...

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire
Advanced Physics Research, EarlyView.According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.
