New surface acoustic wave gas sensor of the mass-sensitive type sensitive to the thermal properties of gasesSENSORS, 2002 IEEE - Tập 1 - Trang 372-375 vol.1
The basic principles of a new surface acoustic wave (SAW) gas sensor are described. Being essentially a sensor of the mass-sensitive type, the proposed device possesses certain features of the thermometric SAW sensors and is not only sensitive to the vapors of volatile substances, but capable of detecting gases by their thermal properties as well. This principles consists of making a certain delay...... hiện toàn bộ

Temperature dependences of fibre-optical sensors of mechanical valuesProceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 3 pp. - 2002
In the work the temperature dependences of the fibre-optical sensor of mechanical values are explored. The examinations of influence of temperature changes on the transmitting characteristic of FOS were spend. As a sensing device the silicon membrane with width h1=40 micron with strong centre by width h3=200 micron was used. The measuring were spend at temperatures T1=20/spl deg/C, T2=60/spl deg/C...... hiện toàn bộ

Principles of torque measurement for rotating microactuatorsSENSORS, 2002 IEEE - Tập 2 - Trang 1757-1761 vol.2
Different micromotors and other rotating microsystems like gearboxes with dimensions of a few millimeters have been developed during the last years. Applications of such micromotors can be found in sensors and actuators for example in medical equipment. These components offer the possibility of extreme miniaturization of mechanical systems with driven rotating parts. The characterization of rotati...... hiện toàn bộ

High-current injection in Spreading-Resistance Temperature sensor on SOIProceedings 2002 IEEE Hong Kong Electron Devices Meeting (Cat. No.02TH8616) - - Trang 69-72
A high-current injection phenomenon was found in Spreading-Resistance Temperature (SRT) sensor on SOI. Simulation and experiment of the sensor with different silicon-film thicknesses and doping concentrations were conducted to demonstrate this phenomenon, which can be explained by the conductivity modulation model normally used in LIGBT. This study is very helpful for designing the operating curre...... hiện toàn bộ

Nanostructured TiO/sub 2/ thin films prepared by supersonic beams and their application in a sensor array for the discrimination of VOCSENSORS, 2002 IEEE - Tập 1 - Trang 647-650 vol.1
In this paper, we present the first sensor ever built using films grown by supersonic beam of cluster oxides as sensing material. Supersonic cluster beams, produced by a pulsed micro-plasma cluster source have successfully used to prepare nanocrystalline thin films of TiO/sub 2/. The sensors, prepared by using different deposition parameters, were suitable for use in a gas sensor array for electro...... hiện toàn bộ

Geometric correction and validation of Hyperion and ALI data for EVEOSDIEEE International Geoscience and Remote Sensing Symposium - Tập 1 - Trang 579-583 vol.1
Precise geometric correction of EO-1's Hyperion data is essential to link ground spectral data and satellite hyperspectral data. Two scenes have been selected from sites of the EVEOSD (Evaluation and Validation of EO-1 for Sustainable Development of Forests) project. One site is the Greater Victoria Watershed District (GVWD) located on south Vancouver Island, BC and the other is Hoquiam located in...... hiện toàn bộ

Prospects of using Si/CaF/sub 2/ structures in pressure sensorsProceedings. 3rd Annual Siberian Russian Workshop on Electron Devices and Materials - Tập 1 - Trang 2 pp. - 2002
The present work examines Si/CaF/sub 2/ structures. Comparative analysis of existing structures of membrane tensoresistive sensors has shown the main obstacle in their developing: a problem of thickness control and reproducibility of an elastic element. It causes large diversity of strain sensor parameters, affects their sensitivity and linear range of transformation. However, SOF structures are v...... hiện toàn bộ
