The paper deals with the investigation of electro-physical properties of Si1-xGex whiskers; the possibility of their use as sensitive elements in magnetic field and temperature sensors is considered. The possible ways of improving the output characteristics of these sensors, particularly through the use of a measuring system with digital signal processing.
Influence of proton irradiation on the properties of Si1-xGex whiskers as strain sensors is studied in this work. On the basis of secondary signal processing the possibility of using such whiskers as a strain sensor’s sensitive element resistant to proton radiation is shown.
The paper describes an automated wireless monitoring system developed for stress-strain state of main pipelines. Since the most damages occur in the main pipelines’ areas of intense plastic deformation, their remote control in such areas is of significant interest, and one of the solutions to the problem is the proposed measuring system based on Si-whisker sensitive elements.
