Modeling and Simulation of Surface Acoustic Wave Chemical Sensors

Husak M., Laposa A., Kroutil J., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

In this paper, we present the design and modeling considerations of SAW (Surface Acoustic Wave) chemical sensors based on various structures. These sensors can be used for identifying environmental contaminants in large applications scale. Various [...]

Gas Sensor with SAW Structures

Laposa A., Husak M., Kroutil J., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

The objective of this paper is presents the modeling and simulation of SAW (Surface Acoustic Wave) gas sensors based on one-port and two-port interdigitated metal structures. These sensors can be used for identifying environmental contaminants [...]

Simple vertical velocity measurement system for different use

Husak M., Jakovenko J., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

The measurement of vertical velocity is necessary for different use. The solutions are based on principle of evaluating the change of an atmospheric pressure. The dependence which evaluates the vertical velocity is derived from the [...]

Micromechanical GaAs Thermal Convertor for Gas Sensors

Jakovenko J., Lalinsky T., Drzík M., Vanko G., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

This paper discusses design, simulation and fabrication of new Micromechanical Thermal Converters (MTCs) based on GaAs developed for Gas sensors. GaAs MTCs seem to be very attractive for design of thermally based MEMS sensor devices. [...]

Design and Characterization of new GaAs Micromechanical Thermal Converter developed for Microwave Power Sensor
