Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

open access: yesAdvanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

open access: yesAdvanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Anomalous Enhancement in MXene‐Based Electrochemical Actuators: Pseudo‐Capacitance‐Induced Multi‐Charge Accumulation in Confined Space

open access: yesAdvanced Science, EarlyView.
We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...

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

open access: yesAdvanced 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 ...
