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 ...
