Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

open access: yesFlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Water‐driven dispersible fiber electrode arrays for position‐dependent intracardiac electrophysiological recording

open access: yesFlexMat, EarlyView.
Abstract Intracardiac electrophysiological recording plays an essential role in identifying abnormal cardiac electrical activity and guiding arrhythmia diagnosis and treatment planning. A key challenge for minimally invasive intracardiac electrodes is to combine reliable transvascular delivery with stable and compliant endocardial contact.

A flexible dual‐gate thin‐film transistor‐based tactile sensor array with polarity‐aware encoding for neuromorphic recognition

open access: yesFlexMat, EarlyView.
A flexible piezoelectric tactile sensor array is developed by integrating polyvinylidene fluoride sensing elements with dual‐gate indium‐tin‐zinc oxide thin‐film transistor‐based pixel amplifiers. Direct coupling to the high‐impedance gate minimizes signal loss, enabling twofold voltage amplification and an extended effective relaxation time of ∼4.86 s

Postoperative Hemoglobin and Transfusion Rates Do Not Influence Revision of Head and Neck Free Flap in a Cohort of 259 Patients

open access: yesHead &Neck, EarlyView.
ABSTRACT Introduction Recent literature advocates restrictive transfusion thresholds (Hb < 7 g/dL). The aim of this study was to evaluate if postoperative hemoglobin levels and transfusions influence Free Flap Revision (FFR). Methods This single center retrospective study included all patients who underwent head and neck surgery with free flap ...

Complication Rates Associated With Evolving Practice Patterns in Vasopressor Use and Fluid Administration for Oral Cavity Cancer Free Flap Reconstruction

open access: yesHead &Neck, EarlyView.
ABSTRACT Background The safety of vasopressors for managing intraoperative hypotension remains debated. This study evaluated complications associated with vasopressor use and fluid administration in oral cavity cancer free flap surgery. Methods Retrospective review of 826 patients who received oral cavity cancer free flap reconstruction from 2008 to ...
