Dynamic Modulation of OECT‐Based Inverters for In Situ Electrophysiological Monitoring

Advanced Science, EarlyView.
This work presents a dynamic gain modulation system for inverter‐based in situ electrophysiological monitoring, enabling long‐term stable signal amplification via real‐time driving voltage adjustment. Moreover, stretchable complementary circuits (inverters, NAND, and NOR gates) are achieved based on a flexible PET substrate and a hexagonal network ...

Highly Stretchable, Adhesive, and Conductive PEDOT Nanocomposite Hydrogels for High‐Performance Flexible Bioelectronics

Advanced Science, EarlyView.
A multifunctional and water‐soluble conductive nanocomposite is fabricated by employing tannic acid‐modified MXene as a template to direct the in situ polymerization of poly(3,4‐ethylenedioxythiophene) (PEDOT). The resulting PEDOT nanosheets are uniformly integrated into hydrogel networks, simultaneously imparting stretchability (>800%), strong tissue ...

Fragmented narrow QRS complex: Predictor of left ventricular dyssynchrony in non-ischemic dilated cardiomyopathy

Indian Heart Journal, 2013
Background: Cardiac resynchronization therapy is an important therapeutic modality in drug refractory symptomatic patients of heart failure with wide QRS (≥120 ms) on electrocardiogram. However, wide QRS (considered as a marker of electrical dyssynchrony)

A rare case of narrow QRS complex tachycardia [PDF]

Netherlands Heart Journal, 2014
The first ECG shows a regular narrow QRS complex tachycardia of approximately 160 beats/min. Clear P waves can be distinguished closely behind each QRS complex. These same P waves appear to be negatively deflected in the inferior leads, which could fit an atrioventricular (nodal) reentrant tachycardia (AVNRT) with retrograde P waves.

A Literature Survey on Potential Private User Information Leakage in Metaverse Applications

Advanced Intelligent Systems, EarlyView.
This survey explores potential privacy risks in the Metaverse, focusing on personal data inferred from virtual reality headsets embedded with passive brain‐computer interfaces (BCI). It reviews how age, gender, and ethnicity can be predicted using neurophysiological signals, (e.g., electroencephalogram). The survey also explores future threats from non‐
