A wireless passive pressure sensor and the measurement system were design and simulated using COMSOL 4.3. The sensor is based on MEMS capacitor attached to a planar inductor for wireless powering and readout. An external coil is used for the measuring system. The pressure to be measured compresses the MEMS capacitor and changes sensor\'s resonance frequency. COMSOL 4.3 was used for the analysis ...

An artificial hand is the one that replaces the hand lost through trauma, disease, or congenital conditions. The proposed design is to simulate a sensor, used in prosthetic hand so as to measure the pressure required to hold the object, using COMSOL Multiphysics®. The physical parameters such as size, shape and mass of the object were optimized so as to hold an object. The weight of the object ...

The current paper focuses on the creation of a consistent environment for the numerical prediction of the physical properties of polymer composite. A limitation factor for the successful simulation of composite processes is the correct estimation of the effective properties depending on several factors such as the constituents (fiber, polymer), the process setup. The numerical prediction of the ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 µm. Such optical sensors include a detector, typically a micro-bolometer, an IR source ...

In order to design an RF MEMS based device, it is beneficial to have information concerning mechanical behavior. For model verification purpose, solution offered by simulation software equipped with predefined physics application is one valuable way to provide initial reference. To avoid unwanted particular total strain in RF MEMS structures, a compensation layer can be utilized. When the number ...
