Self‐Sustaining Sensing Systems: Integration Strategies and Signal–Power Matching in Energy‐Harvesting Electronics

Advanced Science, EarlyView.
Energy‐harvesting‐integrated sensors couple ambient energy conversion with sensing, processing, and wireless communication. This review organizes recent progress through integration architectures and operating principles, revisiting co‐packaged, monolithic, and co‐functional designs together with always‐on, event‐driven, and multi‐modal sensing modes ...

Electron‐Beam Enables Spatially Resolved Defect‐Mediated Work Function Modulation in FAPbI3 Perovskite Thin Films

Advanced Science, EarlyView.
Electron‐beam irradiation enables defect‐mediated work function modulation in metal halide perovskites by regulating interstitial iodides. This approach allows continuous Fermi‐level tuning and spatially resolved formation of lateral surface‐potential‐defined junctions with built‐in potential.

Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors [PDF]

Advanced science
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.

A Bio‐Inspired Visual Sensor With UV‐to‐NIR Fusion for Enhanced Recognition in Autonomous Driving Systems

Advanced Science, EarlyView.
Inspired by the sophisticated multilayer retinal architecture found in Pacific salmon eyes, a novel van der Waals heterojunction sensor based on NbNiTe5/BP is designed. Upon illumination at distinct wavelengths of 365 and 820 nm, the device exhibits distinctive bipolar photocurrent responses with opposite polarities. This unique optoelectronic behavior

Passive Color Imaging Through Macroscopic Strong Scattering Media

Advanced Science, EarlyView.
Light reflected from distant targets is severely attenuated and scattered by dense fog. A color‐channel‐simulated, independently exposed sCMOS array (CISA), combined with a passive colorful de‐scattering pipeline (PCDP), captures and reconstructs extremely weak target signals.

High‐Brightness and Ultra‐Long‐Lifetime Spin Quantum Dot Light‐Emitting Diodes Enabled by Efficient Injection of Spin‐Polarized Holes Through a Hybrid Hole Transport Layer

Advanced Science, EarlyView.
This work employs a hybrid hole transport layer to enhance hole transport efficiency, resulting in improved performance for the final device. It achieves an external quantum efficiency of 6.68%, a circularly polarized electroluminescence asymmetry factor of 0.026, and a high luminance of 14,370 cd/cm2, representing the highest luminance reported to ...
