Tensoresistor-Based Telemetric Strain-Gauge Lens-Less Detectors as Specialized Labs-on-a-Chip for Soil Mechanics and Foundation Monitoring

Abstract

<p>A current trend in the development of the applied measuring techniques is the design of integrated analytical systems on a chip, in particular, labs on a chip based on various physical principles of the substance analysis. Recently, the term "lab-on-a-chip" implied analytical microsystems, requiring macro-scopic readers for the data obtained, which strongly limited the possibilities of their introduction into the field studies and routine analytical measure-ments. However, a progress in the design of telemetric labs on a chip, in-cluding those capable of broadcasting the analytical signal to the receivers with positional sensitivity provided by the use of the labeled counting cham-bers, made it possible to use such devices beyond the scientific laboratories: in the field practice or in monitoring of the natural systems and artificial structures. This can be applied not only to the chemical and biological field measurements, but also to the mechanics, in particular, to geomechanics or soil mechanics. This work briefly considers the results obtained in the Rus-sian laboratory of the second author during the period up to 2011-2013, which have not been published earlier due to the know-how restrictions.</p>
