Bolometer is a thermal infrared sensor used for measuring the intensity of radiation via the heating of a material due to the radiations. A bolometer consists of an absorptive element, a thin layered material, connected to a thermal reservoir. The result is that any radiation received on ... En savoir plus

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 ... En savoir plus

Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... En savoir plus

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 ...

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus

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 ... En savoir plus
