Terahertz (THz) technology has been receiving expanding interest in the recent years due to its rich scientific and potential application. For instance, a variety of semiconductor phonons resonate in the THz range; macro-biomolecules have unique fingerprint lines in the THz range; less ... En savoir plus

A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... En savoir plus

ElectroChemiLuminescence (ECL) is a phenomenon of light emission resulting from an initial electrochemical reaction [1]. Today, ECL is used for detecting biomolecules (DNA, RNA, biomarkers). Unlike other optical detection methods used in biosensors (e.g. fluorescence), ECL is a highly ... En savoir plus

Developing a new loudspeaker design requires not only knowledge and experience in the field, but also an access to verified and efficient tools. HARMAN’s Virtual Product Development (VPD) team has developed a Comsol Application to serve at the early stages of the design process. The app, ... En savoir plus

The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface ... En savoir plus

We present examples of the use of COMSOL Multiphysics for the solution of electrical conduction in varistors coupled to the solution of long-term heat-transport through conduction and convection. We fit measured power-loss and impedance data with analytic functions in order to simulate ... En savoir plus

Mice are important animals used for biomedical research, and are widely used to study various disease models. When studying the behavior of mice and gathering biological data from them, miniature sensors and telemetry devices are needed. These devices must provide continuous monitoring ... En savoir plus

Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power ... En savoir plus

An Acoustic Vector Sensor (AVS) is a compact device used for finding azimuthal as well as elevation angle of an acoustic source using particle velocity and pressure measured at the acoustic center of the device. There are mainly two types of AVS; namely P-P and P-U based AVS. P-P based ... En savoir plus
