Modeling of Vibrating Atomic Force Microscope´s Cantilever within Different Frames of Reference

E. Kamau, and F. Voigt
University of Oldenburg, Germany

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 ... En savoir plus

Simulation of Topology Optimized Electrothermal Microgrippers

O. Sardan[1], D. Petersen[1], O. Sigmund[2], and P. Boggild[1]
[1]DTU Nanotech, Denmark
[2]DTU Mechanical Engineering, Denmark

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 ... En savoir plus

Development and Characterization of High Frequency Bulk Mode Resonators

H. Pakdast, Z. Davis
DTU Nanotech, Technical University of Denmark, Kgs. Lyngby, Denmark

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 ... En savoir plus

Nanofiltration Modeling Based on the Extended Nernst-Planck Equation under Different Physical Modes

J. Gozálvez-Zafrilla, and A. Santafé-Moros
Department of Chemical and Nuclear Engineering, Universidad Politécnica de Valencia, Valencia, Spain

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 ... En savoir plus

Investigating the Use of a Piezoelectric Actuator for the Appendages of a Microrobot

J. Clark, and J. Clark
Purdue University, West Lafayette, IN, USA

We investigate the use of a piezoelectric actuator for the appendages of a microrobot. Possible uses may include micro assembly, mobile surveillance, etc. What is different about this microrobot is that it uses 2 degrees of freedom, low powered piezoelectric flexures, while attempting to ...

Computational Simulation of Electrohydrodynamic Systems Pertaining to Micro and Nano scale Fluid Flow Phenomenon

M. Seiler[1], and B. Kirby[2]
[1]Department of Engineering Physics, Cornell
University, NY, USA
[2]Department of Mechanical Engineering, Cornell
University, NY, USA

Modeling of 3D AC electro-osmotic pumps is relevant to the creation of portable or implantable lab-on-a-chip devices for mm/s tunable fluid flows attainable with battery scale voltages. In this analysis using COMSOL Multiphysics we investigate the modeling challenges of computationally ... En savoir plus

Design of Passive Micromixers using the COMSOL Multiphysics software package

M. Itomlenskis, P. Fodor, and M. Kaufman

Physics Department, Cleveland State University, Cleveland, OH, USA

Relief patterning of the surface of microchannels has been actively pursued as a method of promoting mixing in systems with a low Reynold’s number (<<100). In this work, we explore, by using the COMSOL Multiphysics package and its Chemical Engineering Module, the possibility of ... En savoir plus

COMSOL Multiphysics Simulations of Microfluidic Systems for Biomedical Applications

M. Dimaki, J. Moresco Lange, P. Vazquez, P. Shah, F. Okkels, and W. Svendsen
Department of Micro- and Nanotechnology, Technical University of Denmark, Lyngby, Denmark

The need for fast, easy and cost-effective analysis of blood samples as well as our understanding of the functionality of cells and neurons are two rather pressing issues in the modern world. Both of these can be addressed by functional lab-on-a-chip systems, which have been designed and ... En savoir plus
