Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... Per saperne di più
Introduction In order to understand the detection mechanism of the PZT based nondestructive testing (NDT) technology for interface debonding of CFSTs, numerical simulation on a multi-physical model composed of surface-mounted PZT patches and CFST structural member is established in ...

In this research, we performed multiple COMSOL Multiphysics® simulations. We analyzed the dispersion curves of waves in a LAMB wave pressure sensor; simulated a thin metal film in a microbolometer and observed the resulting stress; investigated the thermal behavior of an acoustic wave ...

Numerous sensors based on various sensing principles are used to measure pressures and temperatures in wellbores. Of all these sensors, piezoelectric quartz is the most preferred means of sensing pressure and temperature and is probably the only sensor to meet stringent downhole ... Per saperne di più
Passing alternating current through a wire placed just above a conducting surface induces eddy currents in that surface. Any cracks present in the conductor modify the eddy current distribution, creating a magnetic field signature unique to the crack. This magnetic signature can be ... Per saperne di più
In this work, a methodology is developed, based on the application of finite element method in the frequency domain, using the COMSOL Multiphyics software, aiming the sensibility analysis of inductance calculation involving some configurations of an E-core magnetic circuit. Such ... Per saperne di più
This work describes the implementation with COMSOL Multiphysics® of a thermal simulation of a space environmental chamber, the SpaceQ chamber [1]. Space environment facilities are needed to simulate on Earth the expected performance of hardware and instrumentation that shall operate in ... Per saperne di più
Here we optimize the geometry: proof mass length Lm to total length L, thickness of the piezoelectric material (Tp) to total cantilever thickness (T) for obtaining the maximum stress distribution (Smax), output voltage (Vout) and power performance (Pout) of the unimorph Cantilever beam ...

Offshore operations, using Robotically Operated Vehicles (ROVs) in areas with high ambient temperatures require ampacity limitations to be established. Specifically, the risk of overheating ROV umbilicals and tethers when running at high power, due to multiple layers on winch drums is a ... Per saperne di più
Load cells are force sensors, which are used in weighing equipment. The objective of this work is to develop MEMS based load cell. In this work two different load cell designs were simulated. First design is based on compressing a meander like polysilicon strain gage for the measurement ... Per saperne di più
