Optimization of a Micro Actuator Plate Using an Evolutionary Algorithm and Simulation Based on Discrete Element Methods

Quinte A., Jakob W., Scherer K.P., Eggert H., Forschungszentrum Karlsruhe, DE

Within the framework of the OMID joint project (1999 - 2002) funded by the BMBF, a universal, fluidically driven actuator plate is being developed in cooperation with the project partners of Bartels Mikrotechnik GmbH and [...]

Use of Numerical Methods for Modeling and Simulating Capillary Driven Flows in Microchannels

Quinte A., Halstenberg S., Eggert H., Forschungszentrum Karlsruhe, DE

Today, medical test strips are used for rapid diagnostics and the quick and easy determination of biomedically relevant parameters, such as the content of glucose of the blood. For the transport of the test uid [...]

Numerical Simulations to Predict the Functionality of Optical Devices

Scherer K.P., Eggert H., Guth H., Sieber I., Stiller P., Forschungszentrum Karlsruhe, DE

At the Institute of Microstructures in the Research Center of Karlsruhe (FZK) optical devices are developed in micro-structure technologies [1]. Because of the miniaturized dimensions of the optical components, a very high accuracy must be [...]

Simulation of a Micro Optical Distance Sensor Realized by the LIGA Process

Guth H., Hellmann A., Sieber I., Eggert H., Mohr J., Nakajima H., Tanimot K., Usami T., Forschungszentrum Karlsruhe GmbH, DE

The aim of the presented work is to simulate and validate an ultra miniaturized optical distance sensor, which works by means of triangulation. The sensor is dedicated for a detection range of 1 to 6mm [...]

Design Optimization of Microsystems

Eggert H., Guth H., Jakob W., Meinzer S., Sieber I., Süß W., Institut fur Angewandte Informatik, DE

At systems level, however, the extreme complexity of FEM models (many network nodes, long computer times) requires the use of models determined analytically. As the complexity of the search space of such analytical models becomes [...]
