Advanced Science, EarlyView.This manuscript presents the WDMS platform, an AI‐assisted, self‐powered wearable dual‐mode sensor for tele‐neurology. It integrates a contact–separation TENG insole with stretchable polyurethane optical‐fiber strain sensors to synchronously track plantar pressure and lower‐limb muscle deformation.

Microwave switching power divider [PDF]
, 1981 A pair of parallel, spaced-apart circular ground planes define a microwave cavity with multi-port microwave power distributing switching circuitry formed on opposite sides of a thin circular dielectric substrate disposed between the ground planes.

Smart Optogenetics for Real‐Time Automated Control of Cardiac Electrical Activity
Advanced Science, EarlyView.We are able to stop dangerous heart‐rhythm spirals before they fully form. Within about 100 ms, it pinpoints the spiral's tiny central tip (≈0.9 mm) using light‐based sensing and machine learning, then shines targeted light to shut it down. This fast, precise, closed‐loop approach detects, targets, and terminates arrhythmias in real time.

Avalanche noise in submicrometre pin diodes
Electronics Letters, 1997 It is shown that recent measurements of noise suppression in thin GaAs pin diodes by Hu et al. (1996) can be explained as a dead space phenomenon and are consistent with the /spl alpha///spl beta/ ratio approaching unity at high electric fields.

Advanced Science, EarlyView.A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...
