Animal model of assessing cerebrovascular functional reserve by imaging photoplethysmography [PDF]

open access: yesScientific Reports, 2020
AbstractAssessment of the cerebral blood-flow-reserve in patients with cerebrovascular diseases is extremely important in terms of making prognosis, determining treatment tactics, and controlling the revascularization outcome in the case of reconstructive interventions on the brain vessels.

Silicon‐Embedded Multifunctional Heterogeneous Integration for Miniaturized Photoplethysmography Detection Devices

open access: yesAdvanced Science, EarlyView.
ABSTRACT The multifunctional integration of chips with high flexibility and scalable manufacturing is crucial for enhancing chip performance, reducing chip size, and simplifying chip design. However, balancing volume, cost, flexibility, and functionality using traditional heterogeneous integration methods is challenging.

Analysis of differences between contact and non-contact estimation of blood pressure

open access: yesCurrent Directions in Biomedical Engineering
Blood pressure (BP) is a key indicator for cardiac diseases. Although many current works focus on estimating BP using photoplethysmography (PPG), the number of works using imaging PPG, i.e.

Artificial intelligence for adaptive neuromodulation in drug‐resistant epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects nearly one third of people with epilepsy and is associated with substantial cognitive, psychiatric, and mortality burdens. For patients who are not candidates for resection or laser interstitial thermal therapy, neuromodulation therapies such as vagus nerve stimulation, deep brain stimulation, and ...

Recent advances in organic broad‐spectrum photodetection materials and devices

open access: yesInfoMat, EarlyView.
Graphical Abstract This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.
