Modeling of Silicon Piezoresistive Pressure Sensor: Application to Prevent Some Diabetes Complications

F. Kerrour[1], A. Beddiaf[1], M. Benabbas-Marir[1]
[1]MODerNa Laboratory, University Mentouri, Constantine, Algeria

Several analytical solutions describing the mechanical behavior of a silicon micro membrane deflection, perfectly embedded and subjected to a uniform and constant pressure have been proposed. The obtained results are compared with those obtained by using COMSOL software for a rectangular ... Mehr lesen

Development of Female and Male Thermoregulatory Models using COMSOL

Stefan Gutierrez¹, Juliette Jacques¹, Timothy Rioux¹, John Castellani ¹, Xiaojiang Xu¹
¹US Army Research Institute of Environmental Medicine, Natick, MA, US

Introduction Most current thermoregulation models represent the body in significantly simplified forms, e.g., cylinders or spheres. These simple geometries do not fully represent the complexity of bones, organs, etc. contained in the human body. Modern medical technologies allow for more ... Mehr lesen

BI Dry 3.0 - A COMSOL App for Simulating Concrete Drying

³Heidelberg Materials Cement Sverige AB, Stockholm, Sweden
⁴Lund University, Lund, Sweden

Curing concrete is best achieved by keeping it nearly saturated at an appropriate temperature until all the cement has fully reacted. However, when installing flooring materials that require low relative humidity (RH) in the concrete, the slab needs to dry as quickly as possible. ... Mehr lesen

Lumped Model of Condenser Microphone with both Sound and Vibration Sensitivities

René Christensen¹, Gojko Obradovic²
¹Acculution ApS
²Oticon A/S

Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... Mehr lesen
