Metal-dielectric composites of epoxy matrix and nickel nanoparticles (up to 40 vol.%) were prepared. Their dielectric and magnetic properties were investigated in the frequency range from 10−2 Hz to 1010 Hz. Electrodynamic parameters (reflection coefficient and absorption) of composites were calculated in dependence on the frequency (106 Hz to 1010 Hz) and nickel content. Possible applications of...
The new results of the single-crystalline zinc oxide nanorods synthesis on the lithium niobate substrate by the hydrothermal growth using zinc acetate as a precursor for both seed-layer and nanostructures array, are presented. The formed nanostructures could be applied as a sensing element for acoustic wave based sensors.
This paper presents a new wide-range sensor for measuring of the gas flow. The flow meter was developed on the base of the new way of measurement, which makes adaptation of measuring procedure. It extends the measurement range of the sensor without losing of accuracy. The sensor is implemented on the basis of the thin-film MEMS structures and the system on a chip, thus minimizing the number of components...
This paper offers a new Smart Sensor of natural gas leak, which was realized on base of a new way of measurement, modern thin film MEMS (micro-electro-mechanical systems) structure and PSoC (programmable system on chip).The senor is a continuous operation device destined for gas leak detection and signal injection that is proportional to concentration of gas in air. If concentration is dangerous the...
On the basis of the Programmable System-on-Chip (PSoC) and thin-film MEMS structure the Smart Pressure Sensor was developed by using newest method of definition of gas pressure. This sensor have such advantages before analogues as high accuracy of transformation, stability of characteristics, durability, presence of a set of standard digital and wireless interfaces. On the basis of one chip PSoC all...
Presents the fundamental conceptual positions of creation of regional information networks on the basis of MITRIS system. It is shown, that such a network allows the establishment of a uniform teleinformation space in Ukraine.
