In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft tissue properties Modeling of moving loads in the TMJ Robust 3D models from imaging data Model of primary ...

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and deposition phases of the process. On a first approach COMSOL Multiphysics® was used to describe and analyze the ...

Introduction: This study describes a thin and low-cost capacitive pressure sensor in touch mode (TM) for monitoring fluid pressure from 0 to 40kPa in fluidic chambers with Luer fittings for medical applications. TM provides good linearity, large measuring range and large overload protection . The choice of a thin polymer membrane as sensitive element with printed circular electrodes reduces ...

The main reason for stent implantation is to provide mechanical support to the arterial wall. So it is important to consider the different mechanical properties of different stent materials while studying the stent implant’s efficacy. The present study gives a comparative overview of mechanical aspects of different stent materials which are most commonly used in angioplasty. Deformation ...

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal neurons and retinal ganglion cells (RGC) in order to restore vision. In this paper, the electrode-tissue ...

A simple steady-state photo-fermentative biochemical model was developed using the COMSOL Multiphysics'® Transport of Diluted Species physics interface. A dimensionless model seeks optimal physical parameters based on given biochemical parameters found in literature. A parametric sweep of the physical parameters is enabled without altering the mesh. Other limitations can be easily added to this ...

To prevent further complications in diabetes, proper management of blood glucose levels is essential. By using ultrasonic transceivers (both transmit and receive) the glucose level of human blood can be determined. By using this ultrasonic technique miniaturized sensors for non-invasive monitoring blood glucose levels. In this paper Barium Titanate (BT) thin film was used as a transmitter and ...

This paper utilizes COMSOL Multiphysics® software and the Application Builder to simulate neurological responses in nerve axons due to external electrical stimuli. The AC/DC Module of the COMSOL® software is first used to solve the Maxwell's equations. Then the results from the Maxwell's equations are used to drive a second model constructed using global equations using the Global ODE and DAE ...

The consequences of hip fracture and femoral fracture are widely known. The mechanical strength of the femur varies in every person, but it is possible to predict the mechanical resistance with parameters like density, dimensions and mineral content. This paper uses different models and empirical studies to determine the mechanical properties of the human femur, developing isotropic and ...

This paper explores surface charge modulated ionic conductance of closed solid-state nanopores for explaining significant nonlinear length dependent variation in ionic current in such nanopore biosensors with a view to design improved sensors without increasing fabrication cost for biomolecule detection. Although extensive work has been done in modeling open pore conductance, closed nanopores ...
