In this work a bulk Silicon MEMS single-axis 8-beam accelerometer has been designed utilising meander beams in the Structural Mechanics and MEMS Module of COMSOL Multiphysics® as shown in Fig. 1.a. To obtain further insights into the design of the accelerometer, an electrical lumped ... Mehr lesen
Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... Mehr lesen
This work focuses on the numerical analysis conducted on the prototype sensor for the measurement of highly concentrated radiative heat fluxes, based on an inverse heat transfer method, realized at the ENEA Portici Research Center in collaboration with the DETEC department of the ... Mehr lesen
The transducer's construction used for current measurement in medium voltage power lines for current values kA is shown. The transducer involves magnetic circuit with a gap in which a MEMS structure with a movable cantilever is placed. The beam is made of silicon with a NiFe layer. The ... Mehr lesen
As a part of a lab-on-chip-device, more often it is required to measure dielectric constant of the fluid. For this purpose it is necessary to develop a sensor whose size is compatible with microfluidic channel. The work, presented in this paper, studies effect of the parameters ... Mehr lesen
The scientific method requires techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge [1]. The Oxford English Dictionary defines the scientific method as "a method or procedure that has characterized natural science since the ... Mehr lesen
We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental ... Mehr lesen
An electric micro-resistance sensor that can continuously measure the deformability of a single red blood cell (RBC) in a microchannel and a numerical model that can simulate the resistance and capacitance of the cell membrane and cytoplasm are developed and improved. The resistance ... Mehr lesen
Underwater acoustics is an area that studies the sound propagation in water and the interactions with other objects and water boundaries. There are many technologies available for acoustic exploration of the ocean. Underwater vehicles are robots used in ocean sciences that travel ... Mehr lesen
Electromagnetic and thermal simulations are achieved using COMSOL Multiphysics® with 2D axisymmetrical finite–element method for a percutaneous microwave hyperthermia system with ex–vivo experiments on different biological tissues. Temperature variation and distribution are studied in ... Mehr lesen
