Multi‐Channel Holography Enabled by Interlayer‐Correlated Liquid Crystal Elements for Nested Optical Encryption

ABSTRACT Liquid crystal (LC) planar devices have emerged as an attractive ultra‐thin platform for optical encryption. However, most existing LC‐based holographic encryption schemes rely on conventional multiplexing strategies with limited design freedom and weak interlayer collab...

Construction of In Vitro-In Vivo Correlation (IVIVC) Degradation Evaluation Model of Absorbable PCL/β-TCP Alveolar Bone Repair Scaffold and Exploration of a Biosafety Evaluation Idea Based on “Homeostasis”

Abstract Traditional in vivo degradation assessments for resorbable medical devices face challenges due to extreme durations, high costs, and a lack of criteria for reaching tissue-response steady states. This study investigates a 3D-printed PCL/β-TCP bone grafting scaffold by de...

EPI-Sense: an integrated hemodynamic sensing and analysis system for early pressure injury warning

Pressure injury poses a critical challenge in geriatric care. Current computer-aided diagnosis is limited by an exclusive reliance on surface texture, neglecting subcutaneous hemodynamics essential for distinguishing Reactive Hyperemia from Stage 1 PI and detecting Deep Tissue Pr...
