Temperature dependences of fibre-optical sensors of mechanical values
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......

The effect of external mechanical stress on the fullerite conductivity
Tập 1 - Trang 5 pp. - 2002
The possibility to use powder consisting of fullerite microcrystals as device sensitive in external mechanical load is considered. As we suppose the change of conductivity of fullerite microcrystal powder as function of environmental mechanical stress is useful for creation of nanoscale devices of sensor electronics. This new effect based on changing of intermolecular distance between fullerene mo......

Prospects of using Si/CaF/sub 2/ structures in pressure sensors
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......

The linear piezoresistance effect in p-Ge/sub x/Si/sub 1-x/ alloys
Tập 1 - Trang 3 pp. - 2002
Based un three-band spectrum model taking into account main scattering mechanisms the concentration dependencies of linear piezoresistance coefficients in p-Ge/sub x/Si/sub 1-x/ alloys were calculated. It is shown that the piezoresistance dependence upon the alloy composition X has a non-monotonous character.

Characterization of etched tracks and nanotubules by ion transmission spectrometry
Tập 1 - Trang 4 pp. - 2002
Etched tracks have recently come into the focus of renewed interest, as it has turned out that they have a great future application potential. Therefore it is worthwhile to review the techniques for ion track characterization. Especially, ion transmission spectrometry (ITS) has recently emerged as a new tool for the rapid characterization of both the average diameter and the shape of etched tracks......

Thin films of solid electrolyte BaO(CeO/sub 2/)/sub 0.9/(Nd/sub 2/O/sub 3/)/sub 0.1/
Tập 1 - Trang 3 pp. - 2002
In this paper the results of investigation of the thin films of the solid electrolyte BaO(CeO/sub 2/)/sub 0.9/(Nd/sub 2/O/sub 3/)/sub 0.1/ are presented. The thin films of the solid electrolyte have been made by the thermal resistive sputtering on the silicon and alumina substrates. The Raman spectra of these thin films are studied. The analysis of these spectra shows that the structure of the obt......

Nanotubule formation by heterogeneous nucleation of silver along etched nuclear tracks in polyethylene terephthalate (PET)
Tập 1 - Trang 5 pp. - 2002
Silver nanotubules of 10 /spl mu/m length and 0.2 to 0.5 /spl mu/m diameter were formed by chemical deposition of Ag onto the inner walls of etched tracks in polyethylene terephthalate (PET). The tubule evolution, beginning with silver nucleation from supersaturated solution, proceeding via Ag crystallite growth, and ending with formation of a continuous cylindrical metal film, is characterized by......
