Mokrov E. A., Lebedev D. V., Bazaev V. P., et al. On design and technology improvement of thin-film resistive-strain pressure sensors


The problems of improving the technological level of thin-film resistive-strain Vt and DAV pressure sensors are outlined. These sensor types are widely applied in harsh environments such as aerospace applications. The paper proposes the optimization of sensors layout, and elastic elements profiling subject to width and thickness. The focus is made on vibration stability improvement and the selection of engineering and functional materials. The outlook for thin-film resistive-strain sensors based on carbon nanotubes and C60 fullerene is discussed.
