Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

Advanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

A minimal electrical model of the human heart [PDF]

arXiv
We develop a minimal whole-heart model that describes cardiac electrical conduction and simulate a basic three-lead electrocardiogram (ECG). We compare our 3-lead ECG model with clinical data from a database of Norwegian athletes. The results demonstrate a strong correlation with the ECGs recorded for these athletes.

Wearable Haptic Feedback Interfaces for Augmenting Human Touch

Advanced Functional Materials, EarlyView.
The wearable haptic feedback interfaces enhance user experience in gaming, social media, biomedical instrumentation, and robotics by generating tactile sensations. This review discusses and categorizes current haptic feedback interfaces into force, thermal, and electrotactile stimulation‐based haptic feedback interfaces, elucidating their current ...

Atomically Flat Dielectric Patterns for Bandgap Engineering and Lateral Junction Formation in MoSe2 Monolayers

Advanced Functional Materials, EarlyView.
This study presents a method to create atomically flat dielectric patterns of SiO2 and AlOx for MoSe2 monolayers, forming lateral heterojunctions with minimal strain. The dielectric pattern modulates excitonic properties, contact potential, and carrier dynamics, demonstrating a tunable approach for enhancing the optoelectronic properties of 2D ...

Classification of Arrhythmias Using Linear Predictive Coefficients and Probabilistic Neural Network [PDF]

Applied Medical Informatics, 2013
Cardiac arrhythmia, which means abnormality of heart rhythm, in fact refers to disorder in electrical conduction system of the heart. The aim of this paper is to present a classifier system based on Probabilistic Neural Networks in order to detect and ...

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Remodeling of Cardiac Gap Junctional Cell–Cell Coupling [PDF]

, 2023
The heart works as a functional syncytium, which is realized via cell-cell coupling maintained by gap junction channels. These channels connect two adjacent cells, so that action potentials can be transferred.

Classification of Short Segment Pediatric Heart Sounds Based on a Transformer-Based Convolutional Neural Network [PDF]

arXiv
Congenital anomalies arising as a result of a defect in the structure of the heart and great vessels are known as congenital heart diseases or CHDs. A PCG can provide essential details about the mechanical conduction system of the heart and point out specific patterns linked to different kinds of CHD.
