Microwave impedance microscopy (MIM) is a novel mode of atomic force microscopy that can measure topography and local electrical impedance simultaneously and with nanometer spatial resolution [1]. This technique is typically used qualitatively, identifying defects in nanodevices or ... Per saperne di più
The purpose of the study is to monitor human body hydration for medical monitoring. It has been shown that the hydration of the deep layers of the skin could reflect the hydration state of the body. Therefore a bioimpedance spectroscopy approach is developed in order to evaluate the skin ... Per saperne di più
Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... Per saperne di più
Common mode chokes are used in electrical circuits to filter out the electromagnetic interference (EMI). The goal of this study is to simulate the impedance of the choke within a range of frequency from 0.01 MHz to 50 MHz. In this simulation model the COMSOL® AC/DC Module with magnetic ...

In this paper, we have proposed an impedance biosensor based on polymer nanowire (made of polyaniline) for efficient electric field mediated capture of biomolecules. Existing polymer nanowire based biosensors fail to achieve high sensitivity for low surface to volume ratio as the whole ... Per saperne di più
Excessive vent noise poses a prevalent challenge in various acoustic applications, significantly impacting the performance and user satisfaction of audio systems. This research investigates the efficacy of noise reduction using a lumped speaker model implemented in COMSOL Multiphysics. ... Per saperne di più
Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...

Introduction Polycrystalline single phase materials often display electrical properties that are a function of their grain size. Impedance spectroscopy, an alternating current technique is ideal for detecting the presence of more than one current path and has been used for many years ... Per saperne di più
Metasurface (MTS) antennas are based on the use of special types of scattering surfaces patterned at a sub-wavelength scale with electrically small metallic dielectric inclusions, usually called unit cells [O. Quevedo-Teruel et al., Journal of Optics, vol. 21, 2019]. The radiation ... Per saperne di più
Proton exchange membrane fuel cells (PEMFCs) are promising energy converters, offering both sustainability and efficiency. Achieving optimal performance, however, requires a deep understanding of the underlying cause-effect relationships within the functional layers. One effective ... Per saperne di più
