MEMS Based Silicon Load Cell for Weighing Applications

D. Chauhan[1], B. D. Pant[2]
[1]Kurukshetra University, Kurukshetra, Haryana, India
[2]CSIR- Central Electronics Engineering Research Institute, Pilani, Rajasthan, India

Load cells are force sensors, which are used in weighing equipment. The objective of this work is to develop MEMS based load cell. In this work two different load cell designs were simulated. First design is based on compressing a meander like polysilicon strain gage for the measurement ... Read More

Trapping DNA Molecules in Fluids Using Electrokinetic Effects Generated by Different Electrode Geometries

S. Ghonge[1], S. Kapur [1], S. Banerjee[1]
[1]Birla Institute of Technology and Science, Pilani - Hyderabad Campus, Hyderabad, Telangana, India

In this paper we present results of simulations done to predict the behavior of a system consisting of DNA molecules in an aqueous medium under the combined effect of AC Electroosmosis and Dielectrophoresis (DEP). ACEO is caused by the movement of fluid particles under the influence of ... Read More

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ... Read More

Numerical and Experimental Study of Water Drop Movement Subjected to an Air Stream in Porous Medium

A. Yekta[1], D. Stemmelen[1], S. Leclerc[1]
[1]LEMTA,UMR 7563 CNRS - Université de Lorraine, 54518 VANDOEUVRE-LES-NANCY France

Considering a liquid drop in relative movement with respect to the air flow at uniform velocity, the liquid will be driven to the surface by the viscous friction. Internal vortices will appear inside the drop. This problem has already been studied in fluid mechanics and is well known as ... Read More

Some Commonly Neglected Issues Which Affect DEP Applications

[1]Clemson University, Clemson, SC, USA
[2]TEL U.S. Holdings, Inc., U.S. Technology Development Center, Austin, TX, USA

Dielectrophoresis (or DEP) has been exploited for various micro and nano fluidics applications like patterning, sorting and separation. However, there are several commonly neglected issues in quantifying DEP forces. Such negligence could potentially lead to wrong DEP force predictions ... Read More

Actively Controlled Ionic Current Gating In Nanopores

G. Zhang[1], S. Bearden[1]
[1]Clemson University, Clemson, SC, USA

It is necessary to understand and control nanopore behavior in order to develop biosensors for a variety of applications including DNA sequencing. The fluidics of nanopore devices we fabricated exhibits a range of interesting phenomena, such as enhanced conductance and current ... Read More

Analysis of Dielectrophoretic Force by Using COMSOL

Taewoo Lee[1]
[1]Department of Biomedical Engineering, Yonsei University, Seoul, South Korea

Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap ... Read More

Optical Modeling of Organic Solar Cells Using the COMSOL

Jungho Kim[1]
[1]Department of Information Display, Kyung Hee University, Seoul, South Korea

A solar cell offers a potential solution to energy shortage problems by converting sunlight into electrical power. Organic solar cells (OSCs) are low-cost and versatile, but also tend to be low-efficiency and short-lasted. Three macroscopic parameters determine their power-conversion ... Read More

COMSOL Multiphysics for the Designs and Applications on Biomicrofluidic Chips

I-Fang Cheng[1]
[1]National Nano Device Laboratories (NDL), National Applied Research Laboratories, Taipei, Taiwan

Some types of rare pathogens can be detected and identified in human blood through a low-cost and label-free method. The On-Chip SESR identification process has a fast detection time (about 5 minutes) and a low detection limit. Discrimination of a species is done by sorting red blood ... Read More
