Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, EarlyView.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Reference Spur Reduction Techniques for a Phase-Locked Loop
IEEE Access, 2019 This paper presents the reference spur reduction techniques for an analog phase-locked loop (PLL). A simple leakage compensation loop is proposed, which cancels the leakage current of the PLL loop filter with a negligible power overhead.

An In Situ Embedded B‐MOF Sponge With Shape‐Memory for All‐in‐One Diabetic Wound Therapy
Advanced Healthcare Materials, EarlyView.A smart shape‐memory sponge dressing (P1A3@B‐MOF) is developed for accelerated diabetic wound healing. It achieves pH‐responsive corelease of Zn2+ and salvianolic acid B, synergistically providing antibacterial action, repolarizing macrophages to the M2 phenotype, and promoting angiogenesis.

A grid frequency estimation method based on moving average filter half-tangent phase-locked loop
Diance yu yibiaoThis paper proposes a half-tangent phase-locked loop (HTan-PLL) with a moving average filter (MAF) for estimating grid frequency. The proposed PLL utilizes a half-tangent phase detector (PD) and introduces MAF into the phase-locked loop to address ...

Advanced Healthcare Materials, EarlyView.Zinc‐containing bioactive glass (ZnBG) promotes diabetic wound healing by regulating macrophage extracellular traps (METs). Specifically, ZnBG reduces oxidative stress and inhibits the PAD4 and NLRP3/caspase‐1/GSDMD signaling pathways, thereby suppressing MET formation.
