Electrical impedance tomography is a non-invasive, low-cost medical imaging technique that can be used long term without radiation hazards. We built a model of the torso, and then used COMSOL Multiphysics® to simulate applied current patterns, compute voltages, and find equi-potential ... Read More
The otoacoustic emissions (OAEs) are acoustic signals emitted by the inner ear as a consequence of the activity of a nonlinear feedback mechanism capable of amplifying the signal near to the hearing threshold level. The otoacoustic emissions can be used as an acoustic imaging of the ... Read More
The subject of the interactions between electromagnetic (EM) fields and living cells is a strong issue for several decades [1]. Large number of works have been done to study the EM field penetration and inner induced currents in living microorganisms. Relevant information to be collected ... Read More
This study demonstrates that a multiphysics model of a LiFePO4/Li half-cell can be applied to simulate the impedance results from an EIS. However, it implies that the double layer capacitance has to be taken into account, since it is responsible of the semi-circle in the impedance ... Read More
Induction brazing is a widely utilized joining process in various industries, offering efficient and localized heating for the assembly of diverse components. At Schneider Electric®, this process is used to assemble a silver piece on a copper piece. This work focuses on the advancements ... Read More
To achieve a deeper understanding of the mechanism of the Deep Brain Stimulation (DBS) scientists use more and more numerical simulations. DBS inhibits overreaching brain activity via electric pulses that send into the brain by electrodes. Different electrode parameters such as geometry, ... Read More
Ultrasonic nondestructive testing (NDT) is extensively used in fields like medicine, oil and gas, and aerospace to inspect materials without causing damage. However, developing experimental setups and prototypes can be costly and time-consuming. This study employs advanced computational ... Read More
A model of a cell counter sensor based on Impedance Spectroscopy (IS) has been implemented in COMSOL Multiphysics. The cell counter is a silicon-based microdevice consisting in 3D electrodes placed in a wide microchannel: cells flow in the microchannel through the electrodes to be ... Read More
For active Structural Health Monitoring (SHM), one popular sensor type is the piezoelectric wafer active sensor (PWAS) due to its multi-purpose application as actuator and sensor and its low cost. It is used to generate a wave field, which interacts with the structure and is recorded by ... Read More
Focused Impedance Method (FIM), a new technique of electrical impedance measurement having high sensitivity in the central region, can sense the change in transfer impedance of an object embedded at a shallow depth within a volume conductor of unchanging background conductivity, using ... Read More
