Robust, Breathable and Stretchable Liquid Metal Composite Nanofibre for Physiological Electrical Signal Monitoring

open access: yesAdvanced Science, EarlyView.
A conductive TPU/liquid‐metal nanofibrous film is fabricated via ultrasonic dispersion, electrospinning, and mold imprinting. The film is breathable, stretchable, deformation‐stable, and provides electromagnetic shielding. n‐Butanol encapsulation mitigates liquid‐metal surface tension and improves biocompatibility. Stable ECG, EOG, EEG, and EMG signals

Hardware Acceleration of Stochastic Neural Networks Enabled by Bit‐Cell Level Co‐Design of Magnetic Tunnel Junctions

open access: yesAdvanced Science, EarlyView.
An MTJ‐based probabilistic processing‐in‐memory architecture unites nonvolatile storage, local entropy generation, and stochastic computation within each memory cell. Stored multi‐bit weights are converted directly into programmable stochastic bitstreams, enabling neural‐network inference, adaptive Ising optimization, and uncertainty‐aware Bayesian ...

Intrinsic i$i$‐Wave Altermagnetism in 2D Graphene Superlattices

open access: yesAdvanced Science, EarlyView.
Altermagnetism has so far been mostly proposed in transition metals compounds. Here we show that monolayer and bilayer graphene antidot superlattices realize a carbon‐based i‐wave altermagnet. This is demonstrated with a combination of symmetry analysis, first principles methods and effective models, featuring a six‐fold spin splitting texture in ...

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

open access: yesAdvanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed
