A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal ... 詳細を見る

Microfluidics is the science of manipulating and controlling fluids at the micron scale. Although, fluid flow in standard geometries can be determined easily by analytical methods, a more rigorous computational model is required for custom geometries. Achira’s microfluidics cartridge has ... 詳細を見る

This paper summarizes the main features of the on-interposer micro-thermoelectric sensors (hereafter denoted by µTES) derived by means of simulations done with COMSOL Multiphysics® software. µTES are thermal sensors based on the Seebeck effect which converts thermal flow into electrical ... 詳細を見る

Introduction: RFID system uses a Transponder and the near field communication (NFC) antenna and a matching circuit (Figure-1) in which at least latter two must be optimally designed for a higher efficiency. Typically, RFID antennas are flat inductive coils with 2 to 4 turns and are ... 詳細を見る

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... 詳細を見る

We have modeled surface acoustic wave (SAW) devices composed of piezoelectric materials: aluminum nitride (AlN), lithium niobate (LiNbO3), and quartz. These materials are often used in RF filters and wireless sensors, which require temperature compensation for stability. Using our COMSOL ... 詳細を見る

Introduction: In this project, COMSOL Multiphysics® and SolidWorks® are employed to model and simulate a mechanically coupled MEMS resonator with varying masses. These resonators consist of three main components: springs on each end to allow the structure to move, a shuttle mass for ... 詳細を見る

A device for monitoring the oxygen consumption of cells has been developed, which consists of two parts; a cell culturing platform (CCP) and an oxygen sensing chip. The CCP possesses inlet and outlet pipes to direct the fluid under the test to the cell culturing chamber through the inlet ... 詳細を見る

Piezoresistive pressure sensors have received much attention over the years because of low cost, simple measurement techniques, etc. There is a challenge in design with respect to appropriate positioning, shape and temperature compensation. Different models of piezoresistive pressure ... 詳細を見る

This paper reports the structural solid mechanic simulation of a MEMS out-of-plane platform that provides thermal and electrical isolation for a device built on it. When assemble, the platform lifted for approximately 400 μm above the substrate level. A mechanical stress analysis is then ... 詳細を見る
