A Vertically‐Stacked Optoelectronic Sensor for Localized Hemodynamics Monitoring
Advanced Functional Materials, EarlyView.This work introduces a hemodynamics monitoring sensor that features vertically stacked microLEDs and a heterogeneously integrated photodetector. The vertically stacked microLEDs enable localized measurements, and by designing the interoptode distance according to the depth of the target region, this vertically stacked optoelectronic sensor is ...

Substrate Engineering for Durable Omniphobic Liquid‐Like Surfaces
Advanced Functional Materials, EarlyView.The significant yet less investigated role of substrates in determining the liquid‐repellency and mechanical durability of liquid‐like surfaces (LLSs) is explored. Thick and crack‐free sol–gel silica intermediary layers are developed that can smoothen substrate asperity roughness even at the micron scale, enabling omniphobic polydimethylsiloxane‐based ...
