Fractional dynamical model for the generation of ECG like signals from filtered coupled Van-der Pol oscillators

, 2013
In this paper, an incommensurate fractional order (FO) model has been proposed to generate ECG like waveforms. Earlier investigation of ECG like waveform generation is based on two identical Van-der Pol (VdP) family of oscillators, which are coupled by ...

Estimation of ECG Parameters via Deep Learning based ECG Segmentation Tool for Non-invasive Detection of Glycaemic Events

, 2023
The ECG segmentation tool has been pivotal in determination of fidu-cial points of the ECG beat which can be used to determine the ECG parameters representing the ECG beat and short-term ECG signal.

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

ECG Criteria for the Prediction of Infarct-Related Artery and Impact of Coronary Dominance on ECG in Patients with Inferior ST-elevation Myocardial Infarction

Sakarya Tıp Dergisi, 2020
Background In-stent restenosis(ISR) is a common angiographic finding in patients with previous stent implantation. Although the mechanism and predictors of ISR has been well-defined, after definition of neoatherosclerosis, a new perspective was emerged ...

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

Advanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Conformal Thermoreversible Gelatin‐Based Gel for High‐Fidelity Electrophysiological Recording and Acute Peripheral Nerve Interfacing

Advanced Materials, EarlyView.
A thermoreversible gelatin‐based gel forms a soft, conformal bioelectronic interface on complex biological surfaces. The flowable precursor penetrates hair‐dense regions, solidifies in situ, and maintains low impedance through adaptive contact and hydration retention.
