Introduction: Vibration energy harvester can convert mechanical vibration energy into electrical energy and store it in battery for later use. It can create clean renewable energy from vibration movements such as walking, jumping, running, etc. This can convert energy previously wasted ... En savoir plus
Micro cantilevers are the basic MEMS structures, which can be used both as sensors and actuators. The . The objective of this work is to study concept of pull-in voltage and how to reduce the same. Voltage is applied to upper cantilever beam and lower contact electrode is made as ground. ... En savoir plus
We simulate a Capacitive Micromachined Ultrasound Transducer (CMUT) using COMSOL Multiphysics® software. The CMUT is an electromechanical system, therefore, we couple the physics of electrical and structural mechanics to describe its dynamics. We obtain the distributions of the electric ...

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix ... En savoir plus
Accurate and efficient tracking is important for designing particle accelerators as well as many other applications which use electromagnetic fields to control particles. We have developed a tracking code in MATLAB® Simulink® which uses electric and magnetic fields calculated in COMSOL ... En savoir plus
Electric field distribution along an insulator surface is of prime importance for the long term performance of insulators. In this paper electric field and potential distribution along a standard 33 kV polymeric insulator were investigated under different pollution conditions. Effect of ... En savoir plus
Diabetes mellitus affects 387 million people across the world according to the latest estimates of International Diabetes Foundation. Insulin is one of the major drugs required to keep the glucose level within desired limits in a diabetic patient. Insulin is generally administered to a ... En savoir plus
HIIPER is an experimental space propulsion device using a helicon and an IEC as a plasma generation and acceleration stage, respectively. There is an experiment in progress, but for true rapid iteration and to model the performance of the engine, COMSOL is a strong candidate for ... En savoir plus
