High Performance Magnetic Field Smart Sensor Arrays with Source Separation

Paraschiv-Ionescu A., Jutten C., Ionescu A.M., Paraschiv-Ionescu A., Chovet A., Rusu A., LIS, FR

A new approach to design high performance microsystems is proposed. It is based on the association between a low-cost sensor array and a multidimensional signal processing technique: the so-called 'blind source separation'. In order to [...]

Analytical Study of Vertical Hall (VH)-Devices Using an Adapted Conform Mapping Technique

Besse P.A., Schott C., Popovic R.S., EPFL, CH

We adapt the conforrn mapping technique to the analytical calculation of two dimensional vertical Hall (VH)-devices with five electrical contacts. With our new method the finite size of the two output current electrodes is taken [...]

Semianalytic Modelling of a Magnetic Levitated Disk with Nonuniform Polarization

Michael S., Scheinert G., Uhlman H., Technical University of Ilmenau, DE

A magnetic bearing for a high rotating electromagnetic drived disk with regard to future applications like the Laser-TV is modelled and designed. For modelling of the system consisting of permanent magnets and copper coils a [...]

Sensitivity Calculation Model Using the Finite-Difference Method

Mueller C., Scheinert G., Uhlmann H., Technical University of Ilmenau, DE

The paper describes an approach to general-purpose design sensitivity analysis for electromagnetic devices. Micro system technology often requires the assessment of manufacturing techniques or effects of tolerances. Emphasis is therefore put on the adaptability to [...]

2D Nonlinearity Simulation of the Vertical Hall Sensor Using SESES

Schott C., Randjelovic Z., Waser J-M, Popovic R.S., EPFL, CH

Buried silicon vertical Hall devices have been accurately simulated in 2D under the condition of a varying magnetic field up to 2 Tesla using the numerical FEM device simulator SESESTM. A field dependent Hall scattering [...]

Microwave Short-Range Interferometric Radar

Benlarbi-Delapï A., Cousin J.C., Ringot R., Mamouni A., Leroy Y., IEMN-UMR-CNRS, FR

A contactless short range sensor based on microwave interferometry is aWe to determine the distance to a reflecting area which is perpendicular to the bore sights of the transmitting and receiving antennas. If this condition [...]

Design and Modelling of Optical Microsystems – An Approach to a User-Friendly System Integration Technique

Wächter C., Schreiber P., Karthe W., Elbers J-P, Glingener C., Voges E., Krabe D., Dümcke R., Reichl H., Hagner G., Schröter S., Bartelt H., Stock E.A., Bauer G., Schäfer W., Sickinger H., Schwider J., Fraunhofer-Institut fur Angewandte Optikund Feinmechanik, DE

Optical microsystems usually are of a hybrid nature. They consist of optical components. i.e.micro-optical and or integrated-optical ones, and additionally they include at least mechanical and packaging components. Therefore, a complete design process has to [...]
