Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐

Ultra‐Low‐Strain Calcium and Magnesium Ion Storage Enabled by Tunnel‐Structured MoO3 Positive Electrode

open access: yesAdvanced Energy Materials, EarlyView.
A hexagonal tunnel‐structured MoO3 is nanoparticulated via hydrothermal synthesis followed by ball‐milling. As a positive electrode in Ca and Mg batteries, it delivers superior capacity and structural reversibility, enabling divalent cation intercalation with minimal lattice distortion and no phase transitions.
