Field-effect transistors (FETs) exhibit favourable characteristics for biological and chemical sensing applications, including multi-parameter response, tunable sensitivity, and inherent amplification [1], [2]. As sensors, FETs employ their gate or active channel as a sensing area, where ... En savoir plus
The paper describes how the fluxgate current sensor works and how it is built in the COMSOL Multiphysics® software. Four COMSOL® modules were used: -AC/DC Module: the magnetic field physic is used in order to apply the Ampere-Maxwell’s law to the different sensor components and to the ... En savoir plus
In recent years, conventional rigid and planar sensor devices are gradually substituted by flexible and stretchable alternatives. This paradigm shift has paved the way to entirely new applications, particularly in the field of personalized health monitoring or environmental sensing. ... En savoir plus
Organs-on-Chips (OoCs) are microfluidics-based systems that aim to recapitulate the in-vivo behaviour of specific organs. Using a network of microfluidic channels, OoCs provide a biophysical and biochemical environment to sustain complex 2D and 3D cell cultures systems that recapitulate ... En savoir plus
Diabetes is a metabolic disorder that is on a rising tide. Diabetic patients must regularly monitor their blood glucose levels. One method for designing such a device is using electrochemical principles, specifically amperometry to determine glucose concentration. It is essential to ... En savoir plus
Piezoelectric materials are substances that can convert mechanical energy into electrical energy and vice versa. This is called the piezoelectric effect. When a piezoelectric material is squeezed or stretched, it creates an electric charge. This is because the material's atoms are ... En savoir plus
In this paper, we report FEM studies of the effect of unwanted interfering structural vibrations on the performance of an underwater Acoustic Vector Sensor (AVS) performed in the COMSOL Multiphysics simulation tool. An AVS is a compact sensor that measures a four-dimensional vector ... En savoir plus
Beams-driven structures are structures that use beams to support their weight. The beams are typically arranged in a way that distributes the weight of the structure evenly. Beams-driven structures are often used in buildings, bridges, and other complicated structures. Beams-driven ... En savoir plus
Atomic force microscopy (AFM) has been widely recognized as an essential tool that enables the imaging of surface, measuring and localizing many different forces and becoming a standard technique for force spectroscopy at the nanoscale. While conventional AFM is well-developed, recent ... En savoir plus
Acoustic emissions generated by active defects in structures, like bridges, aircraft, and pipelines, play a crucial role in detecting flaws in their structural integrity by non-destructive evaluation techniques. Commercially used acoustic emission (AE) sensors are made of piezoelectric ... En savoir plus
