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 ...

Highly Sensitive Cuffless Blood Pressure Monitoring with Selective Laser‐Sintered Liquid Metal Conductors

Advanced Functional Materials, EarlyView.
A soft, compact, and cuffless system for continuous blood pressure monitoring using laser‐sintered liquid metal conductors is developed. The stretchability and sensitivity of the device enable real‐time, non‐invasive tracking of blood pressure, including recovery after exercise. This wearable device offers a practical solution for managing hypertension

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 ...
