Effect of Electrical Field Distortion on Particle-Particle Interaction Under DEP
In using DEP for particle manipulation, researchers often use a formula to calculate the DEP forces in which the forces are proportional to the particle radius to the third power. This formula assumes that the electrical field, E, will not be affected by the presence of a particle, no ... En savoir plus
Multiphysics Modelling and Simulation of Implantable Wireless MEMS Capacitive Sensor for Cardiovascular Diagnostics
Monitoring the Central aorta is a more effective way to diagnose cardiovascular diseases than conventional techniques. Approximately, six million people in the world are currently living with aortic aneurysm and every year 750,000 new cases are diagnosed. This paper presents the design ... En savoir plus
Wireless Power and Communications for Implantable Biosensors
Implantable biosensors have the potential to revolutionize the healthcare industry by allowing patients and their health care providers to continuously monitor blood pH levels, pCO2, proteins, metabolites, and a wide variety of other biomolecules. These devices need to operate completely ... En savoir plus
Modeling Plant Morphodynamics in Predefined COMSOL Multiphysics® Interface
We used a predefined COMSOL Multiphysics® interface to imitate biological growth and shape change (morphodynamics). We found a set of parameters that supply observed morphodynamics for an Arabidopsis embryo during its transition from globular to heart stage. En savoir plus
Modelling the Response of Microdialysis Probes in Glucose Concentration Measurement
Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured ... En savoir plus
A Finite Element Model of Shear Wave Propagation Induced by an Acoustic Radiation Force Impulse
Shear wave elastography is an innovative technique used in combination with the traditional ultrasound imaging to improve the specificity of cancer imaging. A two-dimensional finite element model (FEM), composed of realistic boundary conditions, was developed in COMSOL Multiphysics® to ... En savoir plus
Simulating Organogenesis in COMSOL Multiphysics®: Cell-based Signaling Models
Most models of biological pattern formation are simulated on continuous domains even though cells are discrete objects that provide internal boundaries to the diffusion of regulatory components. In our previous papers on simulating organogenesis in COMSOL Multiphysics® (Germann et al ... En savoir plus
Simulating Organogenesis in COMSOL Multiphysics®: Parameter Optimization for PDE-based Models
Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our ... En savoir plus
An Assessment of the Suitability of the Body and Adult Head Coils for Transmission during Paediatric Magnetic Resonance Imaging
MRI offers many advantages over other modalities and its lack of ionizing radiation is important for children, but can be limited by the radio-frequency (RF) coils available. This work calculates Specific Absorption Rate (SAR) and homogeneity of the RF transmit field (B1+) when imaging ... En savoir plus
A Comparison Between an A-V and V Formulation in Transcranial Magnetic Stimulation
The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled ... En savoir plus
