An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring
This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.

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+ 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

The study proposes a fitting curve as a reference to quantify the optimal K+ ratio in K+/Zn2+ mixed electrolyte, thus achieving stable and high‐capacity aqueous zinc ion batteries at each current density. ABSTRACT Incorporating K+ into Zn‐based electrolytes can enhance the performance of aqueous zinc ion batteries, while the lack of a clear rule for ...

Synergistic control of surface uniformity and solid–electrolyte interphase robustness regulates potassium deposition, suppressing dendritic growth and enabling uniform, dense potassium plating. This combined strategy promotes stable interfacial chemistry and homogeneous electric‐field distribution, leading to enhanced reversibility and long‐term ...
