In the decades since humans first went to space, there has been growing interest in utilizing microgravity to improve our understanding in many scientific fields (1). Applied fields have included evolutionary development, cell mechanics and protein crystallization (2-4). Microgravity ... En savoir plus
MEMS Pressure sensors work on the principle of mechanical bending of thin diaphragm under applied load over diaphragm area. The sensitivity of diaphragm is crucial to efficiency of the sensor. It is defined as the increase in deflection of diaphragm as a result of increase in pressure ... En savoir plus
The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... En savoir plus
Approximately 450,000 people worldwide suffering from hearing problems use cochlear implants (http://www.cochlear.com/au/home/connect/cochlear-hearing-ambassador, June 12, 2018). Manual insertion of the cochlear implant during surgery can potentially damage the delicate tissues within ... En savoir plus
The U.S. Army Engineer Research and Development Center (ERDC) is conducting research using infrasound arrays to detect and monitor structures as well as for dynamic structural characterization of large infrastructure. Previous studies have determined that structures radiate acoustic ... En savoir plus
We report the reversible thermoelectric switching [1, 2, 3] induced by a time dependent and frequency domain electric field (or AC voltage) in a microscopic single contact nano-device based on Gold and Vanadium Oxide, which promises potential applications for future information storage ...

Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... En savoir plus
Within the field of microfluidics, scientists and engineers have found ways to manipulate flow at the micron scale in order to downsize standard experimental procedures. These techniques boast faster results while consuming less resources. Microfluidic devices can be used for point-of ... En savoir plus
Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... En savoir plus
Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...
