The multilayer composite single mass cantilever is a MEMS energy harvester structure. The vibrating structure is under vacuum in hermetic MEMS. However, out-gassing during process integration and fabrication would cause air molecules (e.g. hydrogen, nitrogen, argon, water vapor, oxygen, ... 詳細を見る

Aerostatic bearings are widely employed in high-precision systems, particularly in micromachining applications. Their contactless operation eliminates mechanical friction, enabling highly accurate and repeatable motion. This makes them especially valuable in metrology and advanced ... 詳細を見る

This paper introduces a multiphysics simulation framework for examining the impact of mechanical vibrations on lithium dendrite formation in lithium-ion batteries. We connected the lithium-ion battery, solid mechanics, and phase field physics interfaces using a custom model in COMSOL ... 詳細を見る

Excessive air damping can be detrimental to the performance of oscillating MEMS components. Complex systems, such as structures in pre-etched cavities or angular comb-drive scanning mirrors, typically require simulations to reliably evaluate the air damping. The simulated and ... 詳細を見る

For the purpose of investigation the inertial behaviour of the crystalline lens, the COMSOL Multiphysics® software was used to create a 2D multi-physics model of the porcine eye globe, by using the Fluid-Structure Interaction (FSI). The geometry of the porcine eye model was adapted from ... 詳細を見る

A compression driver is a certain type of electrodynamic loudspeaker which has a phase plug with slits in front of the diaphragm. The slits are narrow enough that the so-called viscothermal effects are of significant importance. In this paper a 2D axisymmetric finite element model of a ... 詳細を見る

The semiconductor industry is always looking for early anticipation of manufacturing risk, pushing the development of Computer Aided Engineering (CAE) modeling of processes. Robust Chip-Package Interaction requires a deep understanding of thermo-mechanical stresses imposed during the ... 詳細を見る

This paper focuses on the acoustic modeling and simulation of a simplified minute repeater watch using the Boundary Element Method (BEM). The overarching objective is to optimize the hammer's impact location on the watch's gong (timbre) to enhance both the radiated acoustic intensity and ... 詳細を見る

The two most commonly used membrane profiles for sound reproduction of the high frequency audio band are the dome shape and the annular shape. The annular (also known as ring) shape has some different basic design features if compared to a dome with the same outer size. For example, ... 詳細を見る

We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The ... 詳細を見る
