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 ...

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Modifying Electrochemical Doping in Light‐Emitting Electrochemical Cells With Gold Nanoparticles

Advanced Science, EarlyView.
This study shows that gold nanoparticles placed at an electrode can control how electrochemical doping occurs in organic electronic devices. Particularly, in light‐emitting electrochemical cells, by shifting the light‐emitting region, device efficiency is improved without altering the emissive material. This approach provides a simple and effective way
