Sensors have diverse applications ranging from the medical field to space exploration. They convert physical parameters such as temperature, pressure, humidity etc. into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of ... En savoir plus

Two bimorph array facing opposite to each other are designed and attached with metal micro plates. The micro solar cell (or) film can be placed on the top of each plate for storing the energy. With respect to the direction of sun light, one bimorph array receives more energy in the form ... En savoir plus

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 ... En savoir plus

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. ... En savoir plus

Rapid advancements in composites have positioned epoxy resins as a critical material in high-pressure applications such as water transport systems, oil and gas transport, and marine and aerospace applications. Epoxies are preferred over other materials due to their enhanced mechanical ... En savoir plus

Electrodialysis (ED) is a unit operation for the separation of electrolytes with numerous applications in the chemical, food and biotechnological fields. Its modeling requires estimating several parameters and performing many batch desalination experiments (Fidaleo and Moresi, 2005). ... En savoir plus

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 ... En savoir plus

Finite Element Method (FEM) simulations are vital in the design of loudspeakers, providing an efficient alternative to traditional trial-and-error methods. This study aims to advance the understanding and optimization of loudspeaker design focusing particularly on the influence of ... En savoir plus

HETT22 is a software developed through joint efforts by Deflexional and Heidelberg Materials. It enables construction companies to accurately simulate, plan and monitor heat and strength development in concrete after castings. Leveraging the power of the COMSOL Multiphysics® software, ...
