Self‐Powered All‐in‐One Wearable Bioelectronics Driven by Pneumatic Energy Buffering of Daily Footsteps

Advanced Science, EarlyView.
A pneumatic energy‐buffering strategy transforms transient and intermittent footsteps into quasi‐continuous electrical energy for a self‐powered wearable biosensing platform. The footwear‐integrated air‐pumping harvester, combined with the rationally designed power‐management system, powers a wearable ankle PPG device with reduced motion artifacts ...

Damage‐Free Passivation of Ambipolar OECTs with Fluoropolymer Film for Enhanced Performance and Stability Toward Reliable Biosignal Processing

Advanced Science, EarlyView.
A damage‐free iCVD fluoropolymer passivation strategy is introduced for ambipolar vertical OECTs. Vapor‐phase infiltration and thermal annealing induce nanoscale phase separation in the OMIEC channel, enhancing overall device performance. A single‐channel bipolar event‐driven spiking encoder is also demonstrated for electrocardiogram signal encoding ...

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets

Advanced Science, EarlyView.
RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.
