Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field . The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs into the cell in a cancer treatment known as electrochemotherapy . In some cases the direct experimental ...

This paper analyzes the magnetic behavior of electroplated wires. For this purpose the resistance and inductance of single turn loops and coils have been simulated and measured. The measurement is delicate due to the influence of a stray capacitance. We show that the quality factor of magnetic plated loops and coils can be tuned easily by the plating thickness. In addition the quality factor of ...

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 detected. The model allows to evaluate the functionality of the device depending on geometrical parameters and ...

Single coil actuators are representing one important component of ABB’s medium voltage reclosers. Their performance is strongly influenced by the considered material properties as well as by the electronic control units’ properties that will power the actuator. Therefore, this paper focuses on electromagnetic actuators modeling and simulation in COMSOL Multiphysics®.

DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also an overview of mine-clearing tools disturbances on the field generated by DEMETER.

An ion trap resonator, used for mass spectrometry, is investigated. Simulations are used to define the stabilization criterion of ion trajectories by optimization of the electrode configurations. The ion interactions are investigated and shown to help in reduction of ion-diffusion. Space charge effects simulate the induced voltages on pickup electrodes.

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous limitations interms of performance, stability and size. One way to overcome the limitations is to use thin ...

In this study, a detailed finite element model coupling the motion dynamics and electromagnetics of a diaphragm based MEMS vibration energy harvester is presented. The energy harvester converts low frequency vibrations to high frequency response by magnetic actuation of a diaphragm carrying coils. AC/DC, Solid Mechanics and Moving Mesh (ALE) modules are coupled together in one 3-D model to ...

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large size in accordance to scala tympani (ST) with restrictions for deeper insertion in ST thus depriving access to ...

Pulsed eddy current (PEC) is being developed to detect stress corrosion cracks between fasteners on the inner wing spars of the F/A-18 Hornet aircraft. The spars are located below a thick carbon/epoxy wing skin, and so cannot be detected by conventional eddy current techniques without disassembling the wing structure. Also, the effectiveness of PEC to detect defects at greater depths is ...
