From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina
Advanced Functional Materials, EarlyView.Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

ASSGCN Model Based Vibration Signal Reconstruction in Motor Vibration Testing
IEEE Transactions on Industrial ElectronicsFor modern electric powertrain applications(wind, electric vehicles/ships/aircrafts,…), the vibrationanalysis of the electric motor is one of the most importanttasks. Normally, a large number of vibration sensors areplaced evenly around the stator of the prototype to sample the acceleration and vibration signals.

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor
Advanced Functional Materials, EarlyView.Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling
