FEM Simulations on the Effect of the Thermal-induced Surface Stress on Ultrathin Resonators

V. Pini, J. J. Ruz Martinez, E. Gil, M. Calleja, and J. Tamayo
Instituto de Microelectrónica de Madri
IMM-CNM (CSIC)
Madrid, Spain

The detection back-action phenomenon has received little attention in physical, chemical, and biological sensors based on nanomechanical systems. We show that this effect is very significant in ultrathin bimetallic cantilevers, in which the laser beam that probes the picometer scale ... Read More

Using Comsol 4.1 to Build a Transient Model of a Drift Tube Ion Mobility Spectrometer with Improved Performance

J. Langejürgen, P. Cochems, U. Günay, M. Allers, and S. Zimmermann
Leibniz University Hannover
Hannover, Germany

An Ion Mobility Spectrometer is a device to analyze different components of a gas mixture. A feature of this technology is the ultra-low detection limit which can be obtained for most trace gases. Due to a limited resolution which is needed to differ between different components an ... Read More

µHeater on a Buckled Cantilever Plate for Gas Sensor Applications

A. Arpys Arevalo Carreno[1], E. Byas[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Mecca, Kingdom of Saudi Arabia

In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design ... Read More

Ultrasound Pressure Field of a Resonating Piezoelectric Membrane with Three Excitation Electrodes
