This paper presents a methodology towards designing, analyzing and optimizing piezoelectric interdigitated microactuators using COMSOL Multiphysics. The models used in this study were based on a circularly interdigitated design that takes advantage of primarily the d{;sub}33 ... Per saperne di più
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Per saperne di più
Damping is the liminting factor for the reachable maximum deflection. Thus, it is a very important issue for resonant microsystems. In this paper, we present a damping model for out-of-plane comb driven resonant micromirrors. The basic concept of this model is to attribute viscous ... Per saperne di più
The objective of this work has been to realize a feasibility study of a cooling device for a SQUID sensor using liquid nitrogen flowing through micro channels. The design consists of an epoxy cylindrical vacuum vessel skewed by a silicon microchannel heat sink. The SQUID sensor is ... Per saperne di più
Electrowetting occurs with the electrical control of the surface wetting properties through the application of an electric potential. A simulation of electrowetting driven droplet dynamics is performed using the COMSOL Multiphysics level-set method for a sessile droplet and for a ... Per saperne di più
We have implemented a two dimensional chromatography model for the analysis and optimization of structured micro pillar arrays. Dynamic surface interaction of solved molecules is taken into account by the kinetic Langmuir model. Variations of the pillar array geometry lead to deviations ... Per saperne di più
Cantilever vibration modes were simulated with COMSOL Multiphysics. In the 1st approach the model consisted of an excitation piezo, a holder plate and a chip where the cantilever was mounted on. A sinusoidal voltage signal was applied to the piezo in the simulation, which resulted in ... Per saperne di più
In this work, electrothermal microgrippers designed using topology optimization are modeled. The microgrippers are composed of two 5 μm-thick polysilicon actuators facing each other. The gap between the actuators are 2 μm in the initial state and the microgrippers are able to both fully ... Per saperne di più
This article describes the development of a bulk mode resonator which can be employed for detection of bio/chemical species in liquids. The goal is to understand the mechanical and electrical properties of a bulk mode resonator device which exhibit high frequency resonance modes and Q ... Per saperne di più
The most successful nanofiltration models are those based on the combination of the Extended Nernst-Planck equation with the Donnan steric equilibrium. These models have been typically solved by using iterative procedures based on the Runge-Kutta method. Yet, such procedures present ... Per saperne di più
