HIGHLIGHTS
- who: Thibault Retornaz and collaborators from the Laboratoire Chrono-Environnement, UMR CNRS, Besançon, France have published the research: Piezoelectric radiofrequency transducers as passive buried sensors, in the Journal: (JOURNAL)
- what: The authors aim here to demonstrate how acoustic wave sensors provide an ideal match to classical RADAR measurement techniques to provide passive sensors interrogated through a wireless link . To either perform multiple measurements or decorrelate the contribution of each physical quantity - including the distance of the RADAR antenna to the sensor - a differential approach is used. The authors demonstrate that assuming the interrogation range . . .
