A Crack‐Based One‐Dimensional Microspheres Array Enables Thermal–Mechanical Decoupled Dual‐Functional Sensing

Advanced Science, EarlyView.
Inspired by Nostoc, a crack‐based one‐dimensional microspheres array (COMA) sensor is developed, which stabilizes crack geometry under isotropic expansion, enabling a predictable, monotonic thermal response from which true strain can be accurately extracted. The COMA sensor exhibits high sensitivity at ultralow deformation (gauge factor up to 89) and a

A Millimeter‐Scale Implantable Magneto–Mechano–Electric Transducer Based on BTO Piezoelectric Ceramics for Remote Wireless Electrical Stimulation of Injured Sciatic Nerves

Advanced Science, EarlyView.
We report a fully wireless, circuit‐free neural stimulator built on a millimetric magneto‐mechano‐electric (MME) cantilever transducer (3 × 10 × 5 mm) with a barium titanate (BTO) piezoelectric ceramic core. Under low‐frequency alternating magnetic fields, the MME cantilever mechanically oscillates, inducing stress on the BTO element and thereby ...

K+‐Triggered Defect Engineering and Proton‐Coupled Storage in V2O5·nH2O for Advanced Zn‐Ion Thin‐Film and Microbatteries

Advanced Science, EarlyView.
K+ pre‐intercalation in V2O5·nH2O induces interlayer contraction, oxygen‐vacancy formation, and mixed‐valence states, activating defect‐mediated proton‐dominated transport. This enables cooperative H+/Zn2+ storage with enhanced kinetics and stability. The resulting Zn‐based thin‐film and microbatteries deliver high areal energy and capacity, offering a
