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 ... Mehr lesen
A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... Mehr lesen
A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88 ... Mehr lesen
In the presented work the dynamic simulation of a silicon anodization process is performed. Two mechanisms of etch form development (diffusion in electrolyte, current flow) are considered and simulated. Influence of electrolyte conductivity and radius of the opening in the masking layer ...

Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper ... Mehr lesen
An acoustic energy harvesting mechanism at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside a quarter-wavelength straight-tube resonator has been studied using COMSOL Multiphysics 4.3 and compared with experimental data. When the ... Mehr lesen
Transducer optimization is a key aspect for successful development and deployment of advanced sensors, especially when designing 3D structures for harsh environments. For piezoelectric transducers, plate thickness determines the operating frequency of the resonator, which is frequently ... Mehr lesen
An autonomous gas-heater for outdoor environments was selected as a test-case for cogeneration in gas-heaters and stoves, permitting installation and operation without need of an electrical network connection. A thermoelectric generator (TEG) was designed, converting part of produced ... Mehr lesen
We have developed a numerical model to represent the effect of injection test in unsaturated porous and fractured rock mass. The test was conducted at the LSBB (Laboratoire Souterrain à Bas Bruit) site close to Rustrel, Vaucluse, France in the field of the French ANR project called “HPPP ... Mehr lesen
This work is to present an implementation of COMSOL with MATLAB® [1] for the liquid cooling system of a battery pack based on the physics in COMSOL. The m.file of a model of battery module from COMSOL 4.2 is exported and modified to run in MATLAB®, as well as is managed by using another ... Mehr lesen
