High‐Performance Graphene‐Based Gas Sensors with Pulsed Heating and AI Processing
Advanced Sensor Research, EarlyView.Ultra‐low power graphene‐based MEMS gas sensors functionalized with vanadium pentoxide or copper‐manganese oxide are reported. Operated in pulsed heating mode, the sensors produce transient conductance profiles analyzed via discrete Fourier transform and compact neural networks.

A Compact Optical Sensor to Self‐Assess Skin Health after Sun Exposure
Advanced Sensor Research, EarlyView.This work presents a portable, low‐cost device capable of detecting changes in the skin associated with excessive sun exposure through reflectance measurements. In vitro validation experiments in skin‐mimicking tissue phantoms showed the device can detect relative pigmentation changes as small as 5%.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation
Advanced Science, EarlyView.This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Van der Waals Template‐Assisted Growth of Two‐dimensional Sb2S3
Advanced Science, EarlyView.Van der Waals (vdW) template‐assisted growth of atomically thin two‐dimensional (2D) Sb2S3 on monolayer MoS2 single crystals is demonstrated, overcoming its thermodynamically preferred one‐dimensional (1D) growth. The resulting sub‐8 nm nanosheets show uniform coverage, atomically sharp interfaces, and enhanced broadband optoelectronic performance as ...
